Authorities are investigating whether an armed robbery at a Centennial veterinary clinic may be connected to the "32 Bandit."A gunman entered the Coal Creek Veterinary Hospital on Thursday at about 7:30 p.m. and ordered everyone on the floor, demanding money.The gunman escaped on foot with an undisclosed amount of cash.The robbery method is similar to that used by the 32 Bandit and he wore similar clothing -- a white or gray hoodie, a black mask and black gloves.The vet clinic is located at East Smoky Hill and Tower roads, not too far away from where the other robberies occurred.Investigators stressed it was too early to tell if Thursday's robbery was the work of the 32 Bandit."Until we have analyzed all the information from tonight's robbery, we really can't say it's the same person at this point," said Arapahoe County Sheriff's Office Lt. Steve Rolan.In a robbery Wednesday night, the robber was wearing a gray and white-hooded sweatshirt and a black ski mask. Investigators were trying to determine if the gunman was the same man who robbed at least 22 businesses since Jan. 23.When officers arrived, a K-9 unit tracked something in the neighborhood north of the clinic."During that track they were able to locate items that they believe are of evidenciary value to this case," Rolan said.Investigators dubbed the robber the 32 Bandit because had the number 32 on his sweatshirt when he robbed a Subway shop in Aurora.
