ILLEGAL off-road bikers have been warned they are being targeted in a police clampdown.

Hoyland Safer Neighbourhood Team has already seized 11 bikes and issued ten warnings to people using the machines.

Insp Glyn Bates said they would concentrate on the most affected areas and encouraged the public to call in.

"Persistent troublemakers will be targeted and local people are encouraged not to suffer in silence," he said.

"By ringing our contact line on 736457 you can report anyone in your community using their bikes in a way that impacts on your quality of life."
