A girl aged 16 was assaulted by a man in Northampton.
She was walking alone along Billing Brook Road between 10.30pm and 11pm on Sunday when a man followed her and tried to make conversation.
As she reached the footpath area near the back of Crestwood Gardens and Springwood Court, the man grabbed her and dragged her for a short distance.
However she managed to free herself and get away and the attacker ran off towards Billing Brook Road.
The man is described as black, aged about 19, 6ft tall and skinny with a clear complexion. He wore a black hoody with white lettering on the drawstrings and blue tracksuit bottoms.
Witnesses or anyone with information is asked to contact police on 101 or Crimestoppers anonymously on 0800 555 111.
