Police are launching a crackdown in a bid to tackle bike crime - and to help cyclists get their stolen property back if it is taken.
Of the 349 bikes which were stolen from the Hillhead, Partick and Anderston areas between July 2012 and July this year, only eight of the owners were detected.
It is estimated that the stolen property was worth around £250,000.
Inspector Gillian Docherty, of Glasgow West End Police Office, said bike crime was a major issue because of the amount of students in the area.
She said: "We do have the university here, which brings a lot of students in and many of them cycle.
"We have stolen bikes varying in value from £500 to £3000. And the review that was carried out of the 349 bikes stolen last year showed that this amounted to a figure in the region of £250,000. People can sometimes think it's a minor crime but there's a lot of money involved."
To tackle the issue, Glasgow police held an event based in Glasgow's Kelvingrove Park skate park today where cyclists could get a security mark on their bike free of charge.
Residents can get their bike permanently 'tattooed' with a security number and then register their details online.
The scheme, which is used by Metropolitan Police, has been funded by the Hillhead, Partick and Anderston Area Partnership.
Please note this event was held on Saturday 21st of September, not Sunday 22nd as originally suggested.
