A Tokyo man was arrested by authorities after seeking medical treatment for a snake bite from one of the 51 venomous snakes he was illegally keeping in his apartment.

Nobukazu Kashiwagi, a 41-year-old port worker, was bitten on his finger by an eastern green mamba as he tried to feed it.

The eastern green mamba is a highly venomous southeast African snake. Kashiwagi also had another of the world's deadliest snakes, a six-foot, four-inch long black mamba.

Kashiwagi was rushed to the hospital for treatment. He was arrested after he returned home.

A woman was reportedly bitten by another snake at his apartment before this.
