Police officers are patrolling a Sheffield park after a boy reported being grabbed by a man in a mask.
The boy, aged 11, was running with his mum in Millhouses Park when he claims he was grabbed by a stranger.
He told police he was approached by the man when he and his mum became temporarily separated during their run.
The incident is said to have happened close to the entrance to the park, at 9am on Thursday.
Special police patrols were ordered yesterday, with officers hoping to trace people who were in the park when the incident happened.
Parents at local schools were informed of the report made by the boy, which police are treating as ‘an isolated incident’.
Superintendent Colin McFarlane said officers want to speak to witnesses or the man himself to try to establish the exact circumstances surrounding the incident.
“I believe what the boy said. He was obviously upset by it, which is why we had extra patrols there yesterday,” he said.
“We need to establish what the motivation was for what happened.
“It appears the male grabbed the boy’s forearm for a couple of seconds but did not attempt to drag him or pull him anywhere.
“My appeal is to people in the park at the time to come forward, as well as the man himself.”
A police spokesman said: “The incident is said to have happened near the entrance to Millhouses Park.
“The boy had briefly stopped to pick something up when he was approached by the man who is described as being about 5ft 7ins tall.
“The boy was not injured and ran to his mum to raise the alarm.”
