Police are questioning a suspect in a trio of attempted rapes in Queens over a two-and-a-half-hour span, The Post has learned.

The creep, whose name or age was not known, was believed to have first targeted a 20-year-old woman on 104th Street near Jamaica Avenue in Richmond Hill around 10:40 a.m. Thursday, cops said.

Then, around 12:35 p.m. about a mile away, the man walked up to a 14-year-old girl, grabbed her from behind and tried to take off her pants, according to police.

The teen fought back and managed to get away to call the police, cops said.

A half-hour later, the man targeted another woman inside Forest Park, according to police.

The perv attacked the 24-year-old while she was on a trail near Woodhaven Boulevard and Forest Park Drive, knocked her to the ground and pulled off her pants.

She also fought off the man and ran to call the cops.

Police sources confirmed cops were questioning a suspect in connection to the attempted sexual assaults Friday morning.
