A shamed police officer has quit her force after she had sex with a vulnerable abuse victim while on duty.

PC Andrea Griffiths, 44, was set to be sacked for gross misconduct for romping with a crime victim.

But she resigned on the morning of a misconduct hearing - saying she 'deeply regrets' the fling with the man she was supposed to be looking after.

A panel heard PC Griffiths began a relationship with the man who was a victim of historic sexual offences and was 'vulnerable'.

She was accused of having sex with him both on and off-duty. PC Griffiths says she only had sex with the man - known as Mr X - once.

North Wales Police presenting officer Amy Clarke, said: 'She developed an inappropriate personal relationship with a vulnerable male who she was responsible for in 2015.

'Miss Griffiths was tasked with being liaison officer and engaged in sexual activity with him. She agreed further that sexual activity happened on duty.'

Miss Clarke said PC Griffiths joined the police in 2001 and was managing the man because he was an alleged victim of historic sexual offences.

PC Griffiths admitted gross misconduct at the hearing at North Wales Police headquarters in Colwyn Bay.

A statement from PC Griffiths said: 'I recognise I shouldn't have had sexual contact with Mr X on June 29, 2015. I accept gross misconduct and deeply regret that it happened.

'To avoid further embarrassment to everyone I have resigned forthwith from North Wales Police.'

PC Griffiths was accused of having an 'inappropriate association' with the man which later 'developed into an inappropriate sexual liaison both on and off duty'.

The professional standards hearing was told she had 'fallen below professional standards of integrity, authority and courtesy' and shown 'discreditable conduct'.

Panel chair Susan Davies said: 'PC Griffiths knew of Mr X's personal and medical issues while she took part in that sexual activity, whilst on duty.

'She breached standards of honesty and integrity, specifically integrity. She behaved in way that was discreditable to North Wales Police.

'We found that conduct so serious that dismissal would be justified and therefore amounts to gross misconduct.'
