Police in Dundee are investigating 15 housebreakings that have happened in the last two weeks.
Officers are following positive lines of enquiry following the series of thefts.
A force spokesman told Dundee Live how 15 incidents have occurred between 4 June and 16 June.
They have been reported in Dundee, Birkhill, Fowlis, Invergowrie, Kinross and Monifieth areas.
Suspects gained access to commercial garage premises, stealing car keys from offices and then using them to steal customer vehicles.
It is believed that the stolen vehicles have then been used for other crimes of dishonesty, including breaking into shops and domestic residences within the Tayside Division.
DI Allan Thomson said: “These housebreakings have been very damaging for the businesses involved and extensive enquiries are underway to catch those responsible.
“Our enquiries are progressing and I would ask anyone who has seen or heard anything suspicious that might help with our investigation to get in touch as soon as possible.
“I would also like to take this opportunity to encourage all business owners to check that their crime prevention measures are in good working order including any intruder alarms or CCTV.
“Please also check that your premises is locked securely at close of business and customer keys are stored in a secure place.
“Should you wish to receive crime prevention advice for your premises, whether that be physical security, CCTV, secure key storage options or anything else related to keeping your premises safe, please contact our Partnerships, Interventions and Preventions Department.”
