Officers investigating reports of dangerous riding and an attempted theft of a motorcycle in Ferndown and West Parley in Dorset are appealing for witnesses or anyone with relevant dashcam footage to come forward.

Several reports were received by the police between 2pm and 3pm on 30 October of a group of teenagers riding motorcycles in a dangerous manner along Christchurch Road between Bournemouth Airport and Parley Cross.

It was reported the motorbikes were driving at excess speed, weaving in and out of traffic and travelling along footpaths as well as attempting to block other motorists.

Another report was received that the group shouted at a motorcyclist and tried to take his motorbike after blocking his path to stop him.

A further report was received at 10.30pm of a group, believed to involve the same teenagers, shouting abuse at another motorcyclist in New Road in West Parley. The group followed the motorcyclist at speed into Dudsbury Avenue.

The group is described as two motorbikes with two riders on each bike. One of the bikes is believed to be a red Honda CB125F and the other is described as a moped.

The riders, described as aged around 15-17, were wearing balaclavas. None of them were wearing helmets and there were no number plates on the bikes.

The rider of the red Honda is described as being of large build and both the rider and passenger were dressed all in black.
