A detective is accused of leaving work for an hour to have sex with his lover - the third policeman from the same station to face lewd behaviour claims in two weeks.
Detective Constable Damian Cotgreave allegedly used his mobile phone to send obscene pictures and smutty messages to up to a dozen different women while on duty.
On another occasion, he is accused of failing to act after a woman he was in touch with threatened to harm herself.
DC Cotgreave, who has already resigned from the force, is set to face a disciplinary hearing later this month.
If charges are proved against him, he could be barred from ever serving as a police officer again.
