Two Richards High School students and another boy were charged with armed robbery and attempted armed robbery after they allegedly used a pellet gun to try to rob one person, then robbed a youth with the same gun just minutes later on June 29.
Christopher Serrato, 17, Erick Robinson, 17, of Calumet City, and a juvenile were arrested at 4:50 p.m. that day. The three youths allegedly approached a man in the 6600 block of Birmingham Street and demanded his cell phone. One of the boys lifted his shirt to reveal a handgun tucked into his waistband, but the would-be victim did not think the gun was loaded and walked away, police said. The youths the reportedly entered a Chevy Cavalier and left the scene.
Shortly thereafter, three boys riding their bikes near Ridge-Lawn School, 5757 W. 105th St., told police that a Chevy Cavalier pulled up alongside them and that one youth exited the vehicle and punched one of the bike-riders in the stomach. Another one of the alleged offenders then exited the vehicle, displayed a black handgun and demanded a backpack one of the boys was wearing, police said. The alleged victim gave the youths the bag, which contained a wallet and two cell phones, according to police. The alleged robbers then left the scene, police said.
Police later received a call that a man had found a bag containing a black handgun in the parking lot of an apartment building in the 5700 block of Ridgemont Lane. Police went to the location and arrested one of the alleged robbers who was walking near a Chevy Cavalier. Police reportedly found the other two youths in the 5700 block of 108th Street.
Serrato and Robinson were charged as adults. The other boy was charged as juvenile, police said.
