Amanda Bynes accused of shoplifting in New York

Troubled actress Amanda Bynes has been banned from top Manhattan department store Barneys New York after she was allegedly caught stealing a hat during a visit on Wednesday (08Oct14).

The Hairspray star was detained by security guards after she reportedly attempted to walk out of the store without paying for a $200 hat she had placed on her head.

According to TMZ.com, Bynes told the guards she didn't mean to steal anything and had grabbed the hat in a bid to disguise herself after being chased by fans inside Barneys.

Police were called to the scene, but the actress had already been allowed to leave by the time cops arrived.

However, the 28 year old won't be welcome back at the store anytime soon - she had to sign a no-trespass agreement before security officials agreed to let her walk.

The incident took place just two days after Bynes was accused of lashing out at a fan while partying at a nightclub in the Big Apple on Monday (06Oct14). Reports suggest the embattled star lost her temper after realizing she was being photographed by curious revelers.

Bynes, whose erratic behavior last year (13) led to lengthy stint in rehab, returned to Manhattan last week (ends03Oct14), days after she was arrested on suspicion of driving under the influence of drugs in California last month (Sep14).
