A woman who appeared to be in her 40s was arrested this morning for allegedly throwing a brick through the window of the WGN-AM studio on the first floor of the Tribune Tower on Michigan Avenue.
The woman, who was wearing a shirt and a piece of fabric around her waist, was taken away in a squadrol after being detained by three Chicago police officers and several Tribune security guards, according to building security.
"She may be a mental patient," said Chicago Police Officer JoAnn Taylor, a police spokeswoman. "She might be a little sick."
Taylor said the woman was taken to Northwestern Memorial Hospital for an evaluation.
The brick was thrown at the street-level studio about 11 a.m., when host John Williams was on the air.
"I thought it was like a foam...it went right through," Williams said jokingly during a commercial break to about a half-dozen passersby outside the studio.
After throwing the brick, the woman claimed she knew who killed Michael Scott," the Chicago Board of Education president who committed suicide earlier this week, security personnel said.
No injuries were reported.
Mary Bates, a witness, was crossing Michigan Avenue when she heard the woman rambling loudly, shortly before throwing the brick, which she carried in a small, red shopping bag.
The woman asked for her lawyer, and flashed money, security said.
"People were giving her money [while she was] in the middle of the street," Bates said.
