It was only a matter of time before Southern California produced its first skateboard sex bandit.

The LAPD overnight said a serial butt-grabber was on the loose in Van Nuys. And he's allegedly using a skateboard to ride up on victims and then get away. Here's the 411:

The skater, in his early 20s, has ridden up on victims three times in recent days and copped an illicit feel “as he passed,” the department said in a community alert.

He attacks during the walk-to-school hour, cops said.

The assaults happened between 7 and 8 a.m. in an area bordered by Sherman Way to the north, Vanowen Street to the south, Van Nuys Boulevard to the west, and Hazeltine Avenue to the east, according to the LAPD.
