Two children were sexually assaulted in a Somerset park over the Platinum Jubilee weekend.
Avon and Somerset Police are appealing for witnesses to the incident in Victoria Park in Frome at around 4pm on Sunday 5 June.
The force said a man approached two secondary school-aged children at and touched them inappropriately.
The offender is described as a 6ft tall, white man with white hair and a British accent. He is thought to be between 50-65 years old and was wearing glasses.
PC Vittoria Radaelli said: “The victims have shown great strength in coming forward. They are shaken but unharmed and we are offering them support during this time.
“We are asking for the public’s help to identify this man, or for witnesses to come forward, so that he can be brought to justice.
“No child should be subjected to these kind of unwanted advances, and we encourage anyone with information to come forward.”
If you saw anything, or have any information which could aid the investigation, call Avon and Somerset Police on 101.
