A GWENT police sergeant has been sacked for “inappropriate sexual behaviour towards female detainees and colleagues” which took place over a period of 18 years.

Richard Evans, 48, was acquitted in August at Cardiff Crown Court on three counts of sexual assault and committing misconduct in a public office by having sex on duty.

But following a professional standards gross misconduct hearing, Evans, who has 29 years' service with Gwent Police, was dismissed without notice for gross misconduct.

The hearing, held on January 30, upheld 41 allegations, of which 32 were for gross misconduct, and involved “inappropriate sexual behaviour towards female detainees and colleagues,” Gwent Police said.

Gwent Police said the incidents which were the subject of the hearing ranged from 1995 to 2013.

The investigation was initially overseen by the Independent Police Complaints Commission (IPCC), whicho then decided that local investigation was appropriate due to the progress being made.

Craig Guildford, deputy chief constable, said: “Richard Evans’ attitude and behaviour was disgraceful, he abused his authority when dealing with female colleagues and female detainees. He failed to treat them with courtesy and respect, and failed to have regard to the equality and diversity duty in the workplace.

“His immediate dismissal was the only appropriate course of action.”

He added: “Events and investigations like this are thankfully rare in policing, but even one is too many. If anyone has concerns about the behaviour of any Gwent Police staff or officers, I would encourage them contact the Gwent Police Professional Standards Department.”

Jan Williams, Independent Police Complaints Commissioner, said: “Sergeant Evans displayed wholly inappropriate behaviour towards both vulnerable female detainees while in custody, and to female colleagues, and I am pleased he is no longer able to abuse the position of trust he held.

“I give credit to Gwent Police for their diligent and determined investigation into his behaviour, and for reaching this fitting conclusion where he can no longer be a part of the police service.”

She added:”The dismissal should send a message to any police officer that the sort of behaviour shown by this sergeant is utterly unacceptable, and bring confidence to colleagues who witness anything like it to report their concerns.”
