PC Hassan Ali, a member of the police force who was under investigation in relation to the Rotherham child abuse scandal, has died following a car crash.
South Yorkshire Police said the 44-year old police constable was involved in a collision in Sheffield when he was off-duty in January.
He was crossing the road at 10.15pm on Wednesday 28 January when he was hit by a car.
Responding to the death of his colleague, chief constable David Crompton of South Yorkshire Police said: "All of our thoughts are with Hassan's family and on behalf of the force I would like to offer my sincere condolences at this incredibly difficult time.
"PC Ali was a well-liked officer whose colleagues are devastated by what has happened."
PC Ali had been referred to the Police Complaints Commission (PCC) after he had four complaints made against him. One included an incident where he allegedly asked a victim of the sexual exploitation victim out on a date when she was 17 and once more when she was 21, according to the Sheffield Star.
The woman described his actions as "inappropriate and totally unprofessional".
A spokesperson said: "South Yorkshire Police has received four public complaints relating to alleged misconduct of one of our officers.
"The complaints were made by two separate people about the officer, a PC based in the Rotherham area. The force has referred the matter to the Independent Police Complaints Commission.
"The PC continues to work for the force on restricted duties."
