A blue motorcycle was discovered dumped in an alleyway near Garter Court in Luton and police are looking for its rightful owner.
The Yamaha YZS250 motocross was found last month, and did not have a registration plate and the chassis information had been removed.
One person has been arrested on suspicion of theft of a motor vehicle and released on police bail pending further enquiries.
If you are the owner or you know who is, contact PC James Wildman in confidence on 01582 394362 or call Beds Police on 101.
