A police crackdown on bicycle thefts has resulted in dozens of arrests.
The six-week Operation Lathe targeted two-wheel crime across the Granite City.
More than 30 bikes were recovered and 34 people charged.
And detectives are now searching for the owners of £10,000 of high-specification kit that has yet to be claimed.
The operation began at the beginning of June and was extended until yesterday with 12 bikes so far being returned to their rightful homes.
Sergeant Dave Cowie said the remainder included some highly expensive models.
“We have a number of bikes that are still to be reunited with their owners,” he said.
“Some of these bikes are of very high value.
“For example a red and black Giant Defy would have been purchased for around £2,000 and a red Carrera Virtuoso which is valued between £800 – £1,000.
“We still have 19 bikes to return to their owners which collectively are worth around £10,000. “This is valuable property which people will have worked hard for and for a long time to purchase and we would be delighted to see the bikes returned to their owners.
“If you have had your bike stolen recently I would encourage you to contact us as it is possible we may have it.”
Claims will have to be backed up with proof of ownership and photographic identification will be required.
Bikes are kept for three months.
“If you have had your bike stolen recently I would encourage you to contact us as it is possible we may have it. Proof of ownership and photographic identification will be required. Bikes are kept for three months after which “most” will be donated to charity, the force said.
“We continue to encourage you to help us with operations like Lathe by reporting suspicious activity and by ensuring you record all of your bike’s details and distinguishing features including the serial number,” Sgt Cowie said.
“If you security mark your bike’s frame with a UV pen or other method, then if we do recover your bike it means we can return it to you more quickly.
