A 17-year-old Austin male was charged last Wednesday with three counts of armed robbery, earlier confessing to a string of robberies in the northeast section of Oak Park, authorities said.

Oak Park police arrested Jermaine Hall, of the 1000 block of N. Mayfield, Tuesday night on the street near his home, after getting an arrest warrant based on a photo lineup identification by one robbery victim. He was brought to the station and questioned.

Police said Hall, who was also charged on an Illinois Department of Corrections warrant for violating a home detention curfew, confessed in writing to four armed robberies. They conducted a series of physical lineups last Wednesday night before going to the state’s attorney to seek formal charges.

The felony review division of the Cook County State’s Attorney’s Office approved criminal charges for three incidents on the 1000 block of Austin, the 800 block of Hayes and the 600 block of N. Humphrey.

“He was identified in physical lineups,” Det. Cmdr. Clemet Harbour of the Oak Park police said last week, referring to three of the lineups. A victim in the fourth incident did not identify Hall.

All the robberies were committed in daylight by a hooded and masked man armed with a silver handgun.

“He gave us information regarding the gun,” Harbour said, “but the family there is not cooperating.”

Hall was ordered held in lieu of $22,500 bail last Thursday and was formally arraigned the next day at the Maybrook Courthouse. His next court date is Jan. 30.
