Mr . Griffin Mr . Griffin is the Headmaster at Weatherfield High . He visited Gail Platt - mother of mischievious pupil David - with regard to him playing truant from school in June 2006 , and mentioned that he would not have undisciplined children at his school . A couple of days later , Gail and David visited Mr . Griffin at his office , where David claimed that he was being bullied by lads above his year but then refused to give up their names which made Mr . Griffin doubtful of his claims , however Gail was persistent that her son was telling the truth and stated that she would keep David off school until the term ended . A few months later David - under pressure by Mr . Griffin - gave up the names of three lads at the school . In February 2007 , Mr . Griffin sent Cilla Battersby - Brown a letter to come and visit him . When she attended he mentioned how her son Chesney had been deeply affected by her diagnosis of terminal cancer , but Cilla admitted that she had received the all clear . She then left his office feeling guilt ridden at her deception . In June , he went to visit the Platt household over an incident when David had set fire to his exam paper , and told Gail that he had no option but to expel him from the school . Two years later in April 2009 , Mr . Griffin witnessed Chesney ' s older sister Fiz grabbing pupil Kenzie Judd by the scruff of the neck and called them into his office . Despite Fiz stating that Kenzie was bullying Chesney , Mr . Griffin refused to believe them and it came out that he was dating Kenzie ' s mother . An angered Fiz told Mr . Griffin that Chesney would no longer be attending the school and that she would home school him henceforth . Over seven years later in September 2016 , Gary Windass visited the school to report that Bethany Platt was being bullied by a girl named Lauren . As Bethany was in the midst of being harassed by Lauren in the school corridor , an oblivious Mr . Griffin took her into his office where Gary was waiting . Mr . Griffin stated that the school had a strict policy on anti - bullying , although Bethany commented that it wasn ' t working . Gary warned Mr . Griffin that if the problem wasn ' t dealt with , the school would be hearing from his solicitor - a threat that Mr . Griffin did not take well . A week later a meeting was organised between Bethany , her mother Sarah Platt and Lauren and her mother in order to discuss the matter . Bethany explained what had been going on , however Lauren turned the tables on her and claimed she was the one being bullied by Bethany . A heated argument broke out between Sarah and Lauren ' s mum , which resulted in Mr . Griffin ordering them to settle down , before subsequently suspending the two girls . However at the end of the month , more girls came forward and reported Lauren for bullying . Lauren was subsequently expelled from school , much to the anger of her father who began to act hostile , but Mr . Griffin got him to leave with the threat of having him forcefully removed from the premises . After the pair left , Mr . Griffin complimented Bethany , calling her a brave young woman for tacking the bullying and reporting Lauren . List of appearances . 2006 2007 2009 2016
