Amanda Bynes was arrested by police in her Midtown apartment after officers were called there for a report of a disorderly person Thursday night, law enforcement sources said.
When officers arrived at Bynes' apartment on West 47th Street, she threw a bong out the window. She was arrested on a charge of reckless endangerment.
Bynes was taken to Roosevelt Hospital to undergo a psychiatric evaluation, then to a Midtown police station to be processed.
Attorney information for Bynes was not immediately available.
Bynes, whose increasingly bizarre behavior has been the subject of tabloid scrutiny in recent months, is already under probation for driving with a suspended license. The plea deal secured in Burbank, Calif. earlier this month placed Bynes under three years probation.
The former Nickelodeon star also has a DUI case pending in Beverly Hills.
