Seattle police are looking to bust a masked masturbator who has been terrorizing a local home by pleasuring himself outside the front door wearing a ninja suit and toe shoes.

The naughty ninja has been making his nighttime visits to the home near NE 52nd Street and 12th Avenue NE on as many as four occasions since November last year, police said.

The residence is home to students of the nearby University of Washington.

Seattle police are looking for information on the suspect, who masturbated in public wearing a ninja suit

The man was covered from head to toe - except for his eyes, hands, and genitals, which were left exposed

A woman first reported she had witnessed the suspect masturbating outside the home on January 10, police said.

On February 7, the pervert struck again, and this time he was caught on surveillance camera.

Snapshots from the surveillance tape show a man wearing tight, dark clothing that covered his entire body expect for his eyes, hands, and genitals.

The suspect was wearing toe shoes and his face covered by what looks like a tied-up t-shirt.

Though his get-up was described as dark, it appears white in the night-vision footage.
