Car Break In

My car was parked right in front of Captain Kleene laundry, directly opposite of the brand new but yet to be opened police station. The car was left unattended for about 20 minutes. When I returned, noticed car was unlocked. Items stolen: GPS unit inside the glove box and laptop bag (luckily I did not carry my notebook inside). Laptop bag contains office documents, thumbdrives with office and personal documents including scanned copy of IC, photocopy of car insurance policy, and office keys. Staff at the laundry claimed did not see any suspicious activity.
