A laptop, wallet and bank cards were stolen during a break-in at Letterkenny Town Park.
The incident happened last Tuesday evening between 7.40pm and 8.30pm, while the owner of a car was out for a run.
A grey Jansport backpack was taken from the vehicle after the front passenger window was smashed, containing a silver Lenovo IdeaPad Flex 5 laptop and personal items.
The car was parked in the Town Park car park at the time.
