A volunteer cop is set to be hauled before a police disciplinary panel accused of sending indecent videos of himself to a colleague while on duty.

Essex Police special constable James Parker was allegedly wearing his uniform when he sent a clip showing his exposed penis to the female officer via Snapchat.

He is also accused of sending a string of raunchy messages saying he wanted a colleague to perform a sex act on him underneath a table during a police briefing.

Another said he wanted to have a romantic encounter with her in a cupboard at the police station where they worked, it is alleged.

It is not known whether the pair were in a relationship.

The allegations read: "It is alleged you sent a video clip via Snapchat to a female colleague.

"The video was taken on police premises.

"It depicted you in police uniform and your penis was at least partially exposed.

"You sent the video with a sexual motivation."

The second and third allegations said: "The message was to the effect that you wanted her to perform a sex act on you under a table during a police briefing.

"The message was to the effect that you wanted to perform a sex act with that colleague in a cupboard on police premises.

"This was a reference to a sexual act."

The messages are said to have been sent in October and November last year.

Legally qualified chairman Peter Nicholls will oversee the hearing.

He will be tasked to decide whether the officer's actions individually or collectively amounted to discreditable conduct, acting with a lack of respect and courtesy or acting with a lack of integrity.

He could be dismissed from the force without notice or handed a written warning about his future conduct.

Special officers have the same police powers, uniforms and equipment as regular police officers but are unpaid apart from their expenses.

Anyone wanting to apply is warned they are subject to the same standards of professional behaviour as regular officers, whether on or off duty.

The misconduct hearing will take place at Chelmsford Civic Hall next week.
