Sir Peter Fahy, Chief Constable of the Greater Manchester Police (GMP) has entered a plea of not guilty against a charge of section 3(1) HSWA following an incident on 3 March 2012 when an  unarmed man, Anthony Grainger, was shot and killed by an officer during a planned operation to  arrest a group on suspicion of conspiracy to commit armed robbery. It has been alleged  that there  was an unnecessary exposure to risk through deficiencies in the way the operation was planned. Sir  Peter Fahy is being prosecuted as a corporation sole, which is a distinct legal entity. The person holding the office does not share criminal liability or need to appear in court  in person.

In a separate prosecution, three custody officers employed by G4S have been charged with gross  negligence manslaughter following the death of Jimmy Mubenga who died after  being restrained by  the officers on a plane at Heathrow during his deportation to Angola in October 2010. The three  officers, Colin Kaler, Terrence Hughes and Stuart Tribelnig, were charged with manslaughter as alternative charges after the Crown Prosecution Service (CPS) carried out a fresh review of the evidence following an inquest last year which returned a verdict  of unlawful killing, having originally decided to take no action. The CPS confirmed that they  remained of the view that there was insufficient evidence for corporate manslaughter charges to be brought against G4S.
