Baltimore police called in extra officers and arrested at least 10 juveniles Saturday night as a crowd that witnesses described as rowdy and numbering in the hundreds walked around Downtown.
The arrests ranged from curfew violations to disorderly conduct and assault, said Detective Donny Moses, a police spokesman.
The youth massed on downtown streets, from 1st Mariner Arena on the west side to "The Block" on East Baltimore Street, and south through Baltimore's Inner Harbor, Moses said. He couldn't confirm the exact number of youths, though witnesses likened it to one of the stadiums emptying out.
Moses said, "It was definitely a lot — a lot of kids, a lot of police."
Baltimore police spokesman Anthony Guglielmi described the scene as an "abnormally high number of juveniles in the downtown area."
He said police were investigating to determine what drew the teens downtown.
"We've heard informally there was some sort of meet-up on social media," he said.
