Police are advising moped and motorcycle users to keep their vehicles secure and covered following 19 thefts in the St Albans district in two months.
Fifteen of these motorised vehicles have been recovered nearby – dumped, stripped, damaged or burnt out.
At 11pm on July 28, a moped was found burnt out on the Marford playing fields in Wheathampstead. The moped was stolen on July 27.
A motorbike was stolen in Harpenden on July 1. The bike was recovered in a neighbouring street with damage to the steering lock, wires had been pulled out and cut and there was damage to the side of the bike where it had been dropped on the ground.
Between 1.30pm and 6.20am on July 10, a moped was stolen from Curo Park in Frogmore.
St Albans Chief Inspector Lynda Coates said: “Mopeds and motorbikes are being deliberately targeted in our area.
“We are doing everything we can to trace the person(s) responsible but we also need your help to protect your bikes by taking on board some simple crime prevention advice.
“This includes locking your bike and setting an alarm if it has one. Try to park where there is CCTV and use a motorbike cover. If you can, at home, fit special attachments such as ground loops to lock your bike to.
“Please also let us know about anyone acting suspiciously around motorised vehicles, including on CCTV or doorbell cams.”
