Thieves used a child's trampoline to slide eight motorbikes from an industrial unit in Lancashire. The bikes are off-road machines in the process of being turned into on-road bikes, said to be worth about £24,000.

They were taken from a house on the moors behind Lords Hall on Duckshaw Road, Darwen. Police say the thieves must have had a good knowledge of the property to be able to carry out the burglary.

They bike is fitted with Supermoto road wheels and nylon pedals. The owner is offering a £2,000 reward for any information leading to an arrest.
