A deaf man was attacked Thursday by an unknown suspect wielding a knife.

The victim was walking north on South Rogers Street when an older, red pickup truck with a cracked windshield drove by, Lt. David Drake of the Bloomington Police Department said.

The truck made a U-turn and returned to the victim. The suspect exited the vehicle and began yelling at the victim, who could not hear him.

“The victim said that the driver was gesturing like he wanted something from him,” Drake said.

The suspect then cut the victim on his arm with a knife. The victim ran, and the suspect returned to his truck and fled the scene.

The victim was transported to Bloomington Hospital by ambulance and treated for the laceration.

The suspect is described as a medium-built, white male 25-35 years in age, with black hair and a black beard, Drake said.

Anyone with information is encouraged to contact Bloomington Police Detective Rick Crussen at 339-4477.
