An image of a motorcyclist seen riding around a housing estate without a helmet has been issued by police.

Police want to track down the youngster, who was seen in the Woodingdean area of Brighton on Monday afternoon this week.

They say the man, clad in a grey T-shirt and black tracksuit bottoms, was not wearing a helmet as he went through the area.

In a Twitter post the police said: "We would like to find this man after he was riding around Woodingdean.

"He is putting himself and other road users in danger by riding without a helmet.

"If you know this man please get in contact with us."

It follows a spate of similar incidents during a week of road safety patrols by officers. It includes an off-road bike being stopped for having no licence, registration, insurance or helmet in Bevendean on Tuesday.

They also stopped a rider in Coldean on Tuesday because his registration plate was too small. Officers discussed road safety with the lad involved.

Anyone who recognises the man in Woodingdean is asked to contact the police and quote 47180086330.
