A man who was walking in a Northampton park was touched inappropriately.
The incident happened between 5.15pm and 5.30pm when the victim, who is in his fifties, was walking through Eastfield Park when he was approached by two teenage boys. One of the boys made a rude comment and touched him inappropriately.
One boy is described as white, about 5ft 6in with a slim build. He was wearing a dark-blue or black Parker-style coat and had short blonde hair.
The second boy was wearing a dark-coloured coat and had dark hair.
It is believed the two boys were with a group of about six other teenagers who were nearby. All the boys were aged approximately 14 to 17-years-old.
