A surveillance picture released on Wednesday produced a tip call that produced the name of the suspect, investigators said. He is not in custody at this time.
They also linked the same suspects to both rapes for the first time today.
The prosecutor's office says the man attacked a woman from behind and forced her into a building on Bergen Avenue near Fairmont, where he raped her early Sunday morning. Eventually, he was scared off by a neighbor.
The woman told police her attacker was a black man about 5'7, physically fit wearing a short sleeve shirt and a red baseball cap.
He was caught on surveillance camera, shirtless without a cap.
About a half mile away from where Sunday's rape happened, another woman was brutally attacked back in March. She was grabbed from behind and dragged into an alley where she was raped for more than 30 minutes. She gave police a very similar description.
