ROCHESTER HILLS, Mich. (AP) — Four people have been charged with repeatedly stabbing a suburban Detroit man with a screwdriver after authorities say he found them inside his vehicle.

The Oakland Press and The Detroit News report two 20-year-old men, Colin Feeney and Michael Latimer, were charged Friday in a Rochester Hills court with assault and armed robbery. Two teenage girls were charged as juveniles in Oakland County Children’s Village.

Attorneys weren’t present in court for the men.

Judge Lisa Asadoorian, who denied bond for Latimer and Feeney, says Latimer has 16 previous convictions. A juvenile referee also denied bond for the 13-year-old and 16-year-old girls.

The 58-year-old Oakland Township man was taken to the hospital after the Tuesday morning attack. He’s since been released and attended both sets of hearings but declined comment.
