At approximately 2 a.m., a man was walking his 80 pound service dog on Orville Road when a black vehicle occupied by two suspects pulled up next to him. The passenger in the vehicle got out and demanded property. When the man refused to give the suspect any property, the suspect displayed a knife and cut his hand with it. The driver of the vehicle then got out and attempted to assault the man. The man told police that he and his dog were able to fight off the suspects who got in the vehicle and fled without taking anything.
