Frank Foster Frank John Foster was a businessman and co - owner of Underworld who was responsible for raping Carla Connor . After much manipulating and deceiving others , Frank met his end when he was murdered by his mother Anne in the factory . Biography . As an Underworld client , Frank Foster took a shine to Carla Connor ' s PA and sister - in - law Michelle . Carla wanted to make a good impression towards Frank and sent Michelle to go and have dinner and discuss business with Frank in order to secure a contract , which actually occurred on the last night before Michelle ' s boyfriend Ciaran McCarthy was due to leave . Frank however was more interested in discussing other things rather than business . Frank continued his business in Underworld and again took an interest in one of Carla ' s assistants , this time Maria Connor . When trying to secure a deal , Carla sent Maria round to Frank ' s house all dolled up hoping to make an offer . When Maria went round , they shared a few drinks on his sofa , and Frank forced himself on her believing he was onto something , and a distraught Maria left . He returned the next day but Maria tried her best to ignore him , and when Carla asked her later why she was being rude to him , she told Carla everything . Frank later apologised and signed the deal . In March 2011 , he went out on a date with Tracy Barlow who was working at the Rovers . However , Maria later warned Tracy about Frank and him trying to force himself on her , but Frank told Tracy that he had misread the signals and it was a mistake , and they continued to date . Frank later cancelled the order , but after Maria was forced to say sorry by Carla , he decided to go ahead with the contract . Frank ' s relationship with Tracy was short - lived after he dumped her because of her obsession with her ex - boyfriend Steve McDonald . In April , Frank was happy with the deal with Carla . He later offered to buy a share in Underworld , which Carla happily agreed to . Everyone at the factory celebrated Underworld ' s new victory , but Maria wasn ' t happy with it . Maria later packed in her job , and told her boyfriend Chris Gray about what had happened with Frank , which almost led to a fight . Chris told Maria she should call the police on Frank , but she was wary about doing so , although she ended up phoning them after a heated encounter with Carla . The police arrested Frank , but he was later released due to lack of evidence . When Carla learned of the death of her mother , Frank shared his sympathies with her , and after she got heavily drunk at Nick ' s Bistro and later the Rovers , Frank was instructed by Peter Barlow to look after her . Frank took Carla back to his house and allowed her to sleep on the couch . When they arrived for work the next morning together , gossip began to go around , and Maria became convinced they were a couple . While in the Rovers , Chris confronted Frank and began pushing him around , which led to a fight and also a big brawl in the pub . Sometime later , Carla went round to stay at Frank ' s house again and the couple kissed , later starting a relationship . Frank proposed to Carla in the pub , only to be turned down in front of everyone . However , when he kept pushing her in the factory as to why she didn ' t accept , she gave up and accepted his proposal . Frank also got Carla and Leanne Barlow to make up after their feud over Peter . When Frank and Carla celebrated their engagement at the bistro in September , with Frank ' s parents Sam and Anne , Carla ended up getting drunk and having a go at his mother . She then got in their car , despite the fact she was drunk . When he got in the passenger seat , she sped off down the Coronation Street hitting Stella Price and crashing into Barlow ' s Bookies . Frank put Carla in the passenger seat and decided to take the blame . When Stella pulled through , Frank got fined £500 , with £150 for damages and got six points on his licence , much to the anger of Stella ' s partner Karl Munro . Frank also purchased a house for them both . Carla then began to have second thoughts about their relationship and got in touch with her solicitor , Jennifer Lingwood , to see what she could do about Frank if they split up . She then decided to let him down gently and split up with him the day before their wedding . An angry Frank returned to her flat and waited , demanding to know the truth as to whether or not she saw another man . When she confessed to loving Peter , an angered and betrayed Frank raped Carla . He fled and Carla called Maria , who set off to help her at once . They called the police who arrived and took a statement from Carla . Frank then entered the flat acting as if nothing had happened , but DC Malone arrested him on suspicion of attempted rape . He spent a night in the cells while Carla received medical treatment . He was released on bail the following day and after provocation from Frank , Peter thumped him . Peter then followed him onto the street and began to give him a beating . Malone arrived at the scene and arrested Peter for assault . The followed day when Peter was released after also spending a night in the cells , Frank was arrested once again and was denied bail at his hearing . However he later applied for bail and was approved , but couldn ' t go near the factory . He hired his mother Anne to be his proxy at Underworld , much to Carla ' s disbelief , which led to her storming round with Maria , but he then reported her to the police who gave Carla a warning . When Carla lost a client due to a misunderstanding at a meeting , he got his mum and a bunch of men to take away half the machines and materials as he half owned the business so he could set up rival factory Foster ' s . When a struggling Carla had to make cuts , she got rid of a few staff members . Sally Webster was the first to turn to Frank for a job and other machinists soon followed . Frank later started a relationship with Sally . In the weeks leading up to the trial , Frank ' s father died . He hired private investigator Trish Davidson to follow Peter and Carla , and discovered they were having an affair as Trish photographed the couple kissing outside the Chester Parkway Hotel . This evidence was revealed to Peter ' s shocked wife Leanne during the trial , however Frank was subsequently found not guilty for rape . He later hired a woman called Jenny Sumner to con Carla into selling the factory to Frank , promising a better deal . When Sally discovered he intended sacking the staff , she confronted him and he threatened her that the last woman that crossed him paid , which confirmed to Sally that Carla wasn ' t lying . However , it was too late as Carla signed over the factory , and Frank smugly revealed what he had done . Later that day , Carla confronted Frank in the factory to ask him why he did what he did to her , he blamed her and mocked Carla for her alcohol issues . When she called him a rapist , he grabbed her and threatened to rape her again . But Carla escaped him , and Frank was later approached by his mother who was listening from the shadows and was devastated and sickened at him . Frank tried to deny it , but Anne accused him of causing his father ' s death due to the stress of worrying , where Frank mocked her and called her a silly old woman . In complete despair , Anne grabbed Carla ' s bottle which she left behind and hit Frank , causing him to fall down the stairs and die . Anne fled , and Frank was discovered by Sally . Frank ' s body was later taken away from the factory , and a couple of weeks later Anne was arrested after being discovered as the killer . Quotes . " Good to see you Carla .
