Police Sergeant ( Peter Foster ) The Police Sergeant frequently manned the desk at the front of Weatherfield Police Station when residents of Coronation Street had cause , voluntary or otherwise , to enter the station . He was first seen in December 2003 when Katy Harris made an accusation that her father , Tommy , had attempted to murder her boyfriend , Martin Platt , not knowing that the tampering of the brakes on Martin ' s car had actually been carried out by her brother , Craig . Five years later in September 2008 , he was on duty when police officer Mel Morton arrested her own mother for " attempted murder " after Teresa Bryant had plotted to poison Jerry with an overdose of warfarin tablets . Jerry claimed that it had been a misunderstanding so as to protect the children , Kayleigh and Finlay , from the case that would ensue . One month later he was the Custody Sergeant when Becky Granger was arrested several days after she went on a drunken rampage after finding out that boyfriend Jason Grimshaw wanted to rekindle his relationship with his ex - wife Sarah . He was next on duty at the station in January 2009 when Maria Connor turned up to report Tony Gordon ' s confession that he had murdered Jed Stone . Although his manner showed that he treated her report with scepticism , he did arrange for her to see DC Weller . However Maria had been set up by Tony . He had attempted to kill Jed at Christmas but the old man had survived and Tony had then packed him off out of the way to Wigan . When the police investigated Maria ' s claims , which she had also broadcast to everyone in the Rovers , Tony arranged for Jed to make a " surprise " appearance in Weatherfield , thus making everyone believe that Maria was unbalanced and , more importantly , any claims she made that Tony had also murdered Liam Connor ( which he had ) seem equally spurious . In August of the same year , he was on duty when DC Hooch had Becky falsely arrested on suspicion of supplying drugs . DC Hooch had Slug , an old friend of Becky ' s , plant drugs at the Rovers on the day of her wedding to Steve McDonald . In March 2010 , he was manning the front desk again when Nick Tilsley and David Platt called to inquire while their mother Gail McIntyre was being questioned for the murder of recently - deceased husband Joe while in January of the following year he " greeted " Claire Peacock when she came in to confess to assaulting Tracy Barlow , a crime for which Becky McDonald was under suspicion . In September 2011 , he manned the desk when Frank Foster was taken into police custody for the rape of Carla Connor . In March 2012 the sergeant attended to Peter Barlow when he was incarcerated after he confessed to Frank ' s murder , and also dealt with a drunken Sunita Alahan who had climbed on top of a car in the Street and arrested for criminal damage , although she was later released without charge . In January 2013 he was manning the front desk when Tina McIntyre and Tommy Duckworth came to see DS Garrett offer evidence against Kirsty Soames , after Tyrone Dobbs was arrested for allegedly pushing her down stairs and several weeks later took Tyrone into formal custody on the same charge . He was on duty in September of the same year when Jason Grimshaw , Kirk Sutherland along with Beth and Craig Tinker arrived at the station asking to speak to the detective who had worked the Rovers fire case six months earlier , wanting to reiterate the original claims that Karl Munro was responsible for causing the blaze deliberately . In December he was at the desk whilst David Platt arrived and claimed he wanted to report a crime ( being indirectly responsible for his brother Nick Tilsley ' s car crash a few months previously ) . However Nick came along and took David away , not wanting him to go to the police over the incident . In June 2014 he was on duty when a belligerent Rob Donovan demanded to know what was happening to his sister Carla Connor when she was being questioned for the murder of Tina McIntyre , a crime for which Rob was actually culpable . Six months later in December , he booked Roy Cropper into custody and led him to a cell after assaulting Gary Windass with a cricket bat . In a case of mistaken identity , Roy believed Gary to be one of the teenagers who ' d been tormenting him over the past few weeks that had broken into the cafe . Gary was hospitalised with his injuries .
