The City of Beloit Police Department is once again investigating vehicle thefts. The department said they were investigating thefts in the Arrowhead, Bootmaker and Shopiere areas of town. Around an hour later, police released a photo of a possible suspect going through cars from a few days prior. Police say if you know who this man is to contact them. They also suggest doors are locked as windows are not being broken to take items. A series of photos is posted to the City of Beloit Police Facebook page.
