A police warning has been issued after two 'suspicious incidents' in which Sheffield schoolgirls were approached by men in cars.
A 10-year-old girl told police that a car pulled up beside her on Station Road, Woodhouse, and a man she did not know asked her if she wanted a lift.
She said he was in a dark car.
The following day a 15-year-old girl was walking along Drakehouse Lane, Beighton, when a black man in a dark car, possibly an Audi A4, shouted for her to 'get in the car'.
The incidents happened on Wednesday, February 1 and Thursday, February 2.
Inspector Jason Booth, of the Sheffield South East Local Policing Team, said: "We have circulated this information to the other policing areas across the city and ask you be aware.
"No physical attempts have been made to get any kids into cars but we need to be suspicious of this behaviour and ensure both kids and parents are aware."
Anyone with any information should call South Yorkshire Police on 101 and quote incident number 235 of February 2.
