Tommy Harris Tommy Harris ( previously Nelson ) was played by Thomas Craig , and made his first appearance on 13th November 2002 . Biography . Tommy and his wife Angela , along with their children Katy and Craig moved to Weatherfield in November 2002 , having rented 6 Coronation Street and using the surname " Nelson " . They originally came from Sheffield where Angela worked in a pub . She witnessed a murder and gave evidence against the accused . The family of the accused took their revenge with threats and eventually tried to burn their house . The Harrises were taken under the Witness Protection programme , given a new identity as the Nelson family and moved to Weatherfield . Tommy was a trained mechanic ( and Sheffield Wednesday F . C . supporter ) and was soon hired by Kevin Webster at Coronation Street Garage , using references that the Witness Protection program supplied . Not long after , Kevin found a wallet containing a union card with the name " Tommy Harris " on it . Tommy took it when he found it lying where Kevin had left it but Kevin , when realising that Tommy had the wallet , accused him of stealing the wallet from a customer . Tommy couldn ' t explain and was sacked . Eventually however , Tommy took Kevin into his confidence and was re - hired . In April 2003 , Katy slipped away to see her mates in Sheffield and was followed by the brothers of the man who was jailed on Angela ' s evidence . There was a showdown and Tommy was shot in the process , nearly losing his arm in subsequent surgery . The family stayed in Weatherfield even though their cover was blown and resumed using the name Harris . Near the end of 2003 , Tommy and Angela split up . Katy took up with Martin Platt and though disapproving , Angela could not bear to be estranged from her daughter . Tommy was adamant that if Angela was going to keep in contact with Katy , he was not going to be a part of it . Angela left the house briefly but returned and insisted that Tommy left . Tommy began drinking and eventually Kevin had no choice but to let him go . Tommy lived in the flat over Street Cars , jobless for a while . Shortly before Christmas 2003 , Craig , upset that his family seemed torn apart because of Martin , rigged the brakes on Martin ' s car . He told his father what he ' d done , but before it could be righted , they saw Katy drive off with Martin and they followed them . After Katy got out of the car , she saw her father following Martin and called him to warn him . She thought Tommy was going to kill Martin but Tommy was trying to get Martin ' s attention to make him pull over . The brakes failed before that could happen and Martin crashed the car . Tommy pulled him out before the car exploded but later took the blame for the rigged brakes so Craig wouldn ' t get into trouble . Craig couldn ' t handle the guilt and confessed to Martin who told the police he knew his brakes were bad and hadn ' t got them seen to . He made an uneasy peace with Tommy and Angela but Tommy still didn ' t like Martin being with his daughter . In 2005 , Katy told Angela and Tommy that she was pregnant and they were not happy . In March , Tommy saw Martin and Sally Webster together and he thought they were having an affair . When Angela overheard something , she too believed it and they told Katy . Because her mother thought the affair was true too , Katy also believed it , left Martin and aborted their baby . Gail told Angela that Sally had an affair but it wasn ' t with Martin . Angela told Katy that Martin was not unfaithful which devastated Katy . Katy went back to Martin to tell him she was sorry but Martin dumped her . Katy then went to confront Tommy ; he kept calling Martin names , so Katy got hold of a wrench , hit him over the head with it and killed him . Tommy saved the lives of some of the Platt family when Richard Hillman drove them into the canal . Quotes . " Right , everybody out . " ( First line ) " It ' s not beyond the realms is it ? I mean everybody knows he likes a bit of school uniform . . . " ( Final line before being murdered by daughter Katy )
