Bail was set at $150,000 Monday for a Chicago man who allegedly robbed a Naperville man at gunpoint over the weekend and then tried to commit a second robbery just a few minutes later, according to DuPage County authorities.

Police say Marquies E. James, 17, approached a man around 10:50 a.m. Sunday as the man was working on a tablet device in his garage in the 200 block of Briarheath Lane, and then James tried to take the tablet.

As James and the man struggled, James allegedly produced a handgun, and then fled with the tablet, prosecutors said. He is accused of approaching someone at gunpoint about 20 minutes later in the 400 block of Apple River Drive, although police say James did not obtain any property.

Police say they spotted James later walking near the 2400 block of Worthing Drive, and after a short chase, apprehended him.

In addition to a charge of aggravated robbery, police charged James with possession of a stolen motor vehicle. James is alleged to have driven to Naperville in a stolen car.

“This alleged brazen behavior, entering someone’s home, threatening them at gunpoint and stealing from them will not be tolerated and will be prosecuted to the fullest extent of the law,” State’s Attorney Robert Berlin said in a statement issued Monday.

Police said they recovered the gun, which they said was a BB gun, along with the tablet reported stolen in the first robbery.

James, of the 6700 block of Campbell Avenue, appeared in bond court Monday. His next court date was set for Dec. 9.
