POLICE are appealing for information to track down people who have been riding motorbikes across the Black Mountains.

Officers said the riders are getting onto the hillside using the public highway and are driving the scrambler-type motorbikes in an anti-social manner.

PC Tom Milton from the Golden Valley Safer Neighbourhood Team said they are riding on land which is part of the Brecon Beacons National Park, which is an offence.

The bikes also have no registration numbers displayed and it is unknown if they have insurance.

PC Milton said they are also causing considerable damage to the hillside.

The last sightings were in Vowchurch at the junction of the B4348.
