Two men accused of robbing two teenagers at gunpoint in downtown Ann Arbor a week ago are scheduled to appear in court for preliminary hearings this week.

Robert King, 19, was arraigned on two counts of armed robbery, felony use of a firearm and possession of a firearm by a convicted felon at the Washtenaw County Jail, Ann Arbor police Det. Bill Stanford said. King remains at the Washtenaw County Jail on $300,000 bond.

Daniel James Pitchford, also 19, faces identical counts of armed robbery and weapons violations and received a $200,000 bond. 

Stanford said King pulled a shotgun and placed it to the head of a 17-year-old boy sitting in a parked car in the 400 block of South First Street at about 7 p.m. last Sunday. A 15-year-old boy is also a victim, Stanford said. 

Both were robbed of an undisclosed amount of cash, but neither was injured.

Officers followed footprints in the fresh snow from the crime scene to a nearby residence where they arrested Pitchford and King.

King was sentenced to probation in November after being convicted of conspiracy to commit armed robbery in Genesee County, prison records show. He violated probation in just one month and was wanted at the time of his arrest, records show.

Police said the teenagers planned to meet the men that evening, but they would not provide further details.
