Investigators nabbed a sicko who attacked two young girls in broad daylight on Brooklyn streets, police said.

Bjorn Daley, 31, of East Flatbush, was identified by the victims — ages 13 and 10 — as the creep who approached them in separate incidents Wednesday.

Daley allegedly first intercepted the 10-year-old near Brooklyn and Kingston Avenues at 10:15 a.m.

The quick-thinking girl screamed, and the brute fled down Kingston Avenue, police said.

Ten minutes later, police sources said, the same pervert grabbed the arm of a 13-year-old girl a few blocks at Maple Street and Kingston Avenue.

Neither victim suffered serious injuries.

Daley was slapped with charges of unlawful imprisonment, forcible touching, sex abuse and acting in a manner that injures a child under the age of 17, said a spokesman for DA Charles Hynes.
