Police searching for a man who sexually assaulted a 14-year-old girl stopped more than 170 cars in Sheffield to question drivers.
The teenager suffered a serious sexual assault in a wooded area between Fox Hill and Edge Well Crescent in an area locally called "the quarry" on 4 November.
On Thursday, motorists were stopped on both streets.
Police want to establish who was in the area at the time.
Chief Inspector Andy Male said officers also spoke to pedestrians during the operation.
He said: "We want to find people who have access to the area to identify potential witnesses or a potential suspect."
The attacker was described as white with a spotty complexion and a "long skinny face".
Police said the man had a pointed dimple chin, was about 18-years-old, slim and between 5ft 4in and 6ft tall.
