Police are appealing for information after an 18-year-old man was assaulted in Bognor Regis.
The victim was walking alone through Church Path - the alleyway between Lyon Street and London Road lorry park- between 9.30pm and 9.45pm on Wednesday (March 14).
He was about mid-way, just north of the entrance to Hotham Park, when he was pushed against a wall and struck once to the left side of his chest.
The victim then offered his wallet containing an ID card and two Burger King vouchers.
The offender - who is described as being of medium build, about 5ft 8ins tall, and wearing a dark hoodie - took this before running south.
If anyone has information relating to this incident they should call Sussex Police on 101 quoting serial number 1570 of 14 March.
