A 45-year-old man was robbed of more than $300 earlier this week following an incident in Three Rivers.
Sheriff Mark Lillywhite said deputies were called at 1 a.m. Monday to an area on U.S. 131 between Michigan Avenue and North Main Street in response to a strong-arm robbery.
The victim was walking north along U.S. 131 when six people exited a vehicle and assaulted him, law-enforcement officials said.
He told authorities the suspects stole $350 in cash from him.
Authorities said he sustained serious injuries to his face, including a chipped tooth and a swollen eye.
