An operation has been launched in Barnsley to tackle nuisance bikers using the Trans Pennine Trail.
Officers mounted the operation following complaints from residents about bikes and anti-social behaviour.
They have increased foot and cycle patrols in a bid to deter bikers from using the trail.
So far two boys under 16 have had their bikes seized in the crackdown.
Police Community Support Officer Stuart Kiley said: “The Trans Pennine Trail is a lovely area of countryside that is enjoyed by so many people.
“It is a shame that a minority are engaging in anti-social behaviour and spoiling the trail for others.
“We won’t tolerate this crime and we will be taking action against those riding bikes in a manner that causes nuisance to walkers and the local community.
