CLEVELAND, Ohio -- A rookie Cleveland police officer shot a 12-year-old boy outside a city recreation center late Saturday afternoon after the boy pulled a BB gun from his waistband, police said.

Police were responding to reports of a male with a gun outside Cudell Recreation Center at Detroit Avenue and West Boulevard about 3:30 p.m., Deputy Chief of Field Operations Ed Tomba said.

A rookie officer and a 10-15 year veteran pulled into the parking lot and saw a few people sitting underneath a pavilion next to the center. The rookie officer saw a black gun sitting on the table, and he saw the boy pick up the gun and put it in his waistband, Cleveland Police Patrolmen's Association President Jeffrey Follmer said.

The officer got out of the car and told the boy to put his hands up. The boy reached into his waistband, pulled out the gun and the rookie officer fired two shots, Tomba said.

Tomba said the child did not threaten the officer verbally or physically.

At least one of the shots hit the child in the stomach. He was rushed to MetroHealth Medical Center in serious condition. His current condition was not immediately known.

As a handful of community activists shouted obscenities from behind a group of reporters, Tomba said the incident was "very, very tragic."

"We don't come to work everyday and want to use force on anybody," Tomba said. "That's not what our job is. We're part of this community."

The department's use of deadly force investigation team, made up of officers from the homicide and internal affairs units, members of the city's Office of Professional Standards and the city and Cuyahoga County prosecutors office, will determine if the officer was justified in shooting the boy.

Tomba promised the investigation would be open.

"When an officer gives a command, we expect it to be followed," Tomba said. "The way it looks like right now, it wasn't followed, but we're going to continue our investigation."

The shooting comes as the U.S. Department of Justice is investigating the department to determine if it regularly uses excessive force against its citizens.
