Amanda Bynes left a trail of destruction at the Ritz-Carlton in NYC -- days before she was taken in on a 5150 hold -- and TMZ has pics of the disaster zone.
Piles of of garbage, ashes, cosmetics, and even a destroyed smoke alarm can be seen in the photos taken inside Amanda's room.
As we reported, Bynes was booted from the posh hotel last Thursday for smoking weed in the room and being rude to hotel staff. Bynes denied the allegations, but the photos paint a pretty damning picture.
The damaged smoke alarm pic is noteworthy -- Amanda's parents say she has a history of disabling the devices because she thinks they're watching her.
Bynes ran up a $9,000 bill over 9 days -- and sources at the Ritz tell us the hotel is still tallying up the room damages.
