Police say they've arrested the man accused of sexually assaulting a 56-year-old woman at South Street Seaport Monday, then flinging her over a railing.

Jackie Barcliff, 44, surrendered in Harlem Friday after seeing his photos on the news, police said. He was charged with rape and attempted murder, according to officials.

After investigating further, police additionally charged him in the rape of a 14-year-old girl on Aug. 12, when he offered the girl a place to stay for the night, then sexually assaulted her.

Early Monday, Barcliff forced the victim to accompany him to the elevated level of the new Pier 15 park overlooking the East River at the seaport, police said. He allegedly raped her there and then threw her over the second-story railing to the ground below.

The victim, an Occupy Wall Street protester, sustained a broken pelvis and other serious injuries, according to police. She told police she recognized him from past demonstrations.

Barcliff was also arrested last December in front of Liberty Plaza for assault and resisting arrest, police said. He's frequented other Occupy Wall Street gathering sites in lower Manhattan.

It wasn't immediately clear if Barcliff had an attorney.
