Police in Woodside, Queens, were shocked to find a suspect in a brutal sex attack still at the scene hours later — allegedly attacking another victim.

Sgt. Christopher Miro and Detective Everett Newman of the NYPD Special Victims Unit were scouring for witnesses and surveillance cameras at 69th Street and 41st Avenue Tuesday when they got their surprise.

A man fitting the first attacker’s description was running up to a 27-year-old woman and throwing her to the ground.

The two officers jumped from their unmarked car and tackled the man, identified as H. Flores-Guerra, 23, of Queens.

Flores-Guerra allegedly struggled as they apprehended him.

He was charged with attempted rape and assaulting the officers.

By early Thursday, he had yet to be charged in the first attack.

In that crime, a 30-year-old woman was walking home from the 65th Street M/R subway station at 2 a.m. Tuesday. As she walked along 69th Street, a male grabbed her from behind, told her not to scream, threw her to the ground and bit and assaulted her.
