Former child star Amanda Bynes was arrested on Thursday evening in New York City, police confirmed to ABC News.

Bynes, 27, was charged with tampering with physical evidence, reckless endangerment and criminal possession of marijuana, NYPD spokesman Det. Brian Sessa told ABC News.

"There was a 911 call at her apartment building that someone was smoking marijuana in the lobby," Sessa said, adding that once police arrived, a building official took them upstairs to her apartment and Bynes let them inside.

"There was a heavy smell of marijuana," Sessa said. "[Then] she took the bong and threw it out the window."

Bynes is still in police custody, according to Sessa.

Bynes, who has previously been charged with DUI, has displayed erratic behavior recently, tweeting provocative photos of herself and dramatically changing her look. However, just last fall, the actress told People magazine that she was "doing amazing," and planning to launch a fashion line.

Messages for Bynes' attorney have not been returned.
