CLEVELAND, Ohio — A group of teens committed six armed robberies in a two-weeks span, including one where a 16-year-old boy sexually assaulted a woman in Ohio City, prosecutors said.

Four people, including two 13-year-old boys, the 16-year-old boy and a 19-year-old man, are in custody, Cuyahoga County Prosecutor Michael O’Malley said Wednesday. The 16-year-old boy was arrested late Tuesday.

The robberies happened from Nov. 21 though Dec. 5, when the 16-year-old carjacked a 25-year-old woman outside a boxing gym and sexually assaulted her, O’Malley said.

“These are very young individuals and what this community has been seeing is a rash of crime, driven by youngsters with guns,” O’Malley said. “What we are seeing is madness and the availability of guns is out of control.”

O’Malley said the group was loosely affiliated and not all were involved in each robbery. The 16-year-old is suspected of being involved in “the majority” of the robberies, O’Malley said.

Cleveland Police Commander Thomas Stacho said detectives identified others they believe were involved in the robberies but have not made any additional arrests.

Both O’Malley and Stacho said the investigation is ongoing and that they believe investigators could eventually pin more armed robberies on the group. Stacho said federal agents helped Cleveland detectives investigate the group.

The robberies mostly happened in Ohio City and other near-West Side communities, where members of the group live, O’Malley said. He said they watched the neighborhood and targeted people walking to their cars, mostly elderly people or women.

Ward 3 City Councilman Kerry McCormack, whose ward encompasses where four of the six robberies happened, said the robberies “shook the community.”

The first robbery happened about 6 p.m. Nov. 21 on West 32nd Street near Church Avenue. Two armed teens walked up to a 28-year-old woman walking to her car parked on the street.

They pointed a gun at her and demanded her keys, according to police. The woman kicked at the robbers, and one punched her in the face, according to police reports. Another grabbed her purse and ran away.

The next happened about 90 minutes later on West 56th and Tillman Avenue. A 22-year-old Lakewood woman reported that four young boys walked up to her, pointed a gun and demanded her keys. One of the robbers ripped the purse off her shoulder, police reports say.

The group jumped into her SUV and sped away. Investigators tracked the SUV’s movement through OnStar, and spotted it later in the day on West 44th Street. The driver sped from officers and later crashed on West 26th Street and Jay Avenue. A 13-year-old boy was arrested at the scene.

Police found the 22-year-old Lakewood’s iPhone in the SUV.

Four robbers about 7 p.m. Nov. 29 carjacked a 60-year-old man outside the popular Ohio City restaurant Momocho. They stole his SUV and sped away.

A 13-year-old boy and a 19-year-old man, Trevon Whetstone, were charged with aggravated robbery in that incident.

About 90 minutes later, two of the robbers botched an attempt at robbing a man and two women in Cleveland’s Tremont neighborhood. The robbers pointed guns at the trio and demanded their car keys. The two women kept walking but the man confronted the robbers.

He smacked one of the boy’s guns away and realized it was plastic, police reports say. The two robbers ran away without stealing anything.

Members of the group about 45 minutes later carjacked a 33-year-old man at gunpoint on Detroit and Clarence avenues. The group stole a 2009 Honda at gunpoint and sped away.

The last happened on Church Avenue between West 29th and West 32nd streets in Ohio City. The 16-year-old boy walked up to a 25-year-old woman after she left a boxing class, pointed a gun at her and demanded cash.

He forced the woman into the backseat of her car, sexually assaulted her and sped away in her car, police said.

Four teens are accused of committing six armed robberies in a two-weeks span in Cleveland and Lakewood, prosecutors say.
