DETROIT (AP) -- Authorities say a man awaiting sentencing in an armed robbery is on the run after stabbing a sheriff's deputy several times in the neck and carjacked a motorist while escaping from a downtown Detroit courthouse.
The escape Monday morning prompted a lockdown of the facility and sparked a manhunt.
Court records say the man, identified by police as 25-year-old Derreck White, was scheduled in court Monday to learn his punishment after being convicted last month of carjacking, armed robbery and firearms charges.
Wayne County Sheriff Benny Napoleon says White had a plastic comb that had been fashioned into a shank. He says the deputy is expected to survive.
Police say White stole a minivan from a motorist near the courthouse and later abandoned that vehicle on the city's east side.
