Sussex police would also like to hear from you if you saw a group of people arguing in the street in Crawley.
At about 10pm on Bank Holiday Monday 25 May a disturbance was reported at the junction of Rona Close and Lismore Crescent involving a number of people.
A vehicle was thought to have been damaged and that at least one person may have been assaulted during the argument.
One man is then believed to have been forced or helped into a silver car, possibly a BMW, which then drove off.
