A Brooklyn man has been arrested for the weekend rape of a woman who was followed into her Bedford-Stuyvesant building, according to cops.

Reynaldo Mayna Cordero, 35, was busted around 10 p.m. Monday and charged with rape as well as two counts each of sexual abuse and forcible touching.

He is accused of approaching the 27-year-old victim from behind on an e-bike around 12:30 a.m. Sunday and initially slapping “the victim’s buttocks” over her clothing before riding away, the NYPD said.

As the terrified woman tried to get back inside her building, Cordero allegedly returned, followed her inside and raped her, cops said.

He then fled in an unknown direction on the bike, according to police, who later released photos of the alleged fiend.

The victim was taken by responders to a local hospital in stable condition.

There is no indication Cordero knew the assaulted woman, sources told The Post.
