There have been three incidents since June, police say, at Wamsley's Car Lot.
The first incident happened around 3:30 a.m. on June 10th.
Investigators say the man threw a fire extinguisher through a front window and stole several items from a window sill.
He was caught on camera wearing an orange and white football jersey with the words "BEL AIR" and the number 13. He was seen driving a way in a light-colored car.
The second incident happened around 6:00 a.m. on August 9th.
Police say the same man shattered a window, then used pliers to take an antique thermometer from the outside wall.
This time, he was wearing a blue jersey with the words "BEL AIR" and the number 21 on the front. He was seen leaving in the same light-colored car.
Then, at around 10:00 p.m. on October 3rd, a man - believed to be the same suspect - stole a Texaco glass glob from an antique gas pump and a Texaco ash tray.
