He wasn’t even wearing a mankini.

A suspect identified as Joshua Mankini was busted for allegedly assaulting a teenage schoolgirl in California after video showed a completely naked man chasing her down the street.

The revealing video obtained by KFSN shows the totally nude man running down a suburban Fresno street in broad daylight on Friday morning chasing a teen as she headed to school.

The final confrontation was blocked by a van, but police say the girl was pulled to the ground and assaulted, managing to escape seconds later, according to KFSN.

Even when the girl and another friend, who was also chased, managed to get to the safety of a car driven by a parent, the suspect ran toward them and started banging on the window, according to cops.

“That’s your biggest fear as a parent right there,” neighbor Steve Alarcon told the station. “That’s scary scary.”

Mankini, 28, was hit with a slew of charges, including assault with intent to commit a felony, false imprisonment with violence, indecent exposure and annoyance or molestation of a child, court records show.

He lives in a group home and managed to disable an alarm to his bedroom window and sneak out of the house, police told the Fresno Bee.

The “mankini,” a Speedo-style bathing suit pulled up over a wearer’s shoulders, was made famous by the Sacha Baron Cohen character Borat.
