Seven mopeds and motorbikes have been stolen across Borehamwood, Elstree, and Radlett in just over a week.

The police have issued a warning to the public after the spate of thefts between September 19 and 25.

The bikes were stolen from Dales Road, Rye Close, and Theobald Street in Borehamwood, as well as in Scrubbitts Square in Radlett and Cavendish Crescent in Elstree.

Officers have since recovered three of the seven stolen bikes.

Hertfordshire Constabulary said it believes the thefts are "opportunistic" and added the majority of bikes stolen were "unsecured".

Police say the bike stolen in Theobald Street on the afternoon of September 22 had been left unattended but officers found the bike two hours later in Torworth Road.

The bike stolen in Scrubbitts Square between September 24 and 25 had been left locked and secured, while one of three bikes stolen in Rye Close was taken from a front garden.

Detective Inspector Baz Kalia said: "In addition to these thefts we have also received reports of suspicious activity around motorcycles and I would urge people to continue to contact us if they witness suspicious activity so that we can attend.

"Whilst are following a number of lines of enquiry, and working to prevent further incidents, I would urge people to follow some simple crime prevention tips. In many of these cases, the motorcycles were left unsecured, providing an opportunity for an offender. If nothing else, always lock your bike and set its alarm if it has one."
