Gardaí have launched a new pilot scheme using "undercover bikes" to bait thieves to steal them - so they can follow suspects with the aid of GPS trackers.
New figures show there were 6,750 bikes reported stolen across the country last year, and more than 2,000 reported stolen already this year.
Gardaí say it is a "Dublin problem", with 34% of all thefts reported in Dublin city centre, 40% in the rest of the Dublin Metropolitan Region and 26% outside of the Dublin Metropolitan Region.
Inspector Liam Geraghty from Pearse Street Garda Station has said that a number of people have been arrested Dublin in recent weeks, as part of the "bait bike" scheme.
"Over 1,600 bicycles have been reported stolen in the Dublin Region so far this year, when you invest in your bike, also invest in the lock, always lock your bike, no matter how quick you think you might be away and also at home or work, always report bike theft and please record the frame number of your bicycle," he said.
