A policeman has resigned after allegedly being found having sex with a female solicitor in a busy police station.

The pair were allegedly found in a compromising position in Swansea's Cockett police station.

South Wales Police said a misconduct investigation into the actions of the officer was underway.

It's understood the pair were discovered in a disused interview room of the John Street station earlier this month in a state of undress.

The force said an officer based in its Western basic command unit or BCU - which covers Swansea and Neath Port Talbot - had since handed in his notice.

A spokeswoman for South Wales Police said: "South Wales Police professional standards department is investigating an allegation of misconduct against a police officer based in the force’s Western BCU.

"The officer has submitted their resignation and a misconduct hearing will be held in due course."
