A 5-foot-long caiman captured inside an East Bay home during a pot bust has died at the Oakland Zoo, officials announced Thursday.

A cause of death was not listed, but authorities said “Mr. Teeth” was in bad shape when he was found critically ill in a Plexiglas tank inside a bedroom.

Oakland Zoo officials said the caiman, which resembles an alligator, was non-responsive when he arrived at the facility on Tuesday.

Alameda County Sheriff's Sgt. J.D. Nelson said 32-year-old Assif Mayar apparently acquired the alligator, named "Mr. Teeth," in 1996 to commemorate the death of rapper Tupac Shakur.

It appears the animal was being used as a deterrent to scare away would-be marijuana thieves.

Sheriff's deputies also found 34 pounds during their probation compliance check in Castro Valley on Tuesday afternoon.

The dried, processed marijuana was found in a bedroom at a home in the 19000 block of Mt. Jasper Drive around 1:30 p.m., along with ‘Mr. Teeth’.

Mayar, was booked into the Santa Rita Jail in Dublin on drug possession and sales charges and will make a court appearance on Thursday, according to the sheriff's office.
