A 14-year-old girl has been indecently assaulted in North Lanarkshire.
Police said the assault took place on a grassy area at the rear of Robert Burns Quadrant in Bellshill at about 2030 GMT on Tuesday.
The girl did not require hospital treatment but was said to be "extremely traumatised".
The man made off towards Glebe Street after the attack. Police said the only description of the suspect was that he was wearing dark clothing.
Det Insp John Jack said: "Extensive inquiries have been ongoing in the Bellshill area since this incident was reported to us and I would urge anyone with information that may assist our inquiries to come forward.
"The area where the incident happened is popular with dog walkers and I would urge anyone who may have been in that area around the time of the incident last night to contact police as they may have unwittingly witnessed something vital to this inquiry."
