Police are keen to speak to a member of the public who intervened after a man was attacked as he walked along a Grimsby bridleway.
The 35-year-old victim was walking alone along the footpath between Brandale Walk and Greatcoates Road, Grimsby at approximately 7pm on Saturday June 27 when he was approached by a man who was known to him, who asked for a beer.
When he replied he did not have any, the offender hit him on the side of the head with a beer can and the victim fell to the ground, where he was kicked and punched, suffering swelling to his cheekbone, a black eye and swelling and bruising to his nose.
A member of the public intervened and the attacker left the scene with two women and a man.
He later realised his mobile phone was also missing.
Officers are keen to speak to anyone who may have seen the incident, but particularly the member of the public who stepped in to help.
Anyone with information is asked to call 101, quoting crime reference number 2122038.
