An Occupy Wall Street protester from Brooklyn has been charged with one sex attack, and is being investigated in another at the demonstrators’ encampment at Zuccotti Park, law enforcement sources said today.

Tonye Iketubosin, 26, of Crown Heights — a worker at the protesters’ makeshift kitchen — was charged with sexual abuse for allegedly groping an 18-year-old protester inside a tent he helped his victim pitch at the rag-tag encampment on Oct. 24.

She told cops the suspect offered to help her pitch a tent at the encampment , but when she later went to go sleep inside, she found him there. He refused her requests to leave teh tent — and instead allegedly grabbed at her thighs and buttocks, she told authorities .

She finally was able to shove him outside the tent, she told cops.

The woman told cops about the pervy protester on Tuesday night — telling officials she knew the man by sight, but was not acquainted with him.

Iketubosin was apprehended shortly after the complaint, is awaiting arraignment tonight.

Sources said he has no criminal record.

But he’s also being looked at in another 18-year-old woman’s claim that she was allegedly raped inside the suspect’s tent at the encampment last Saturday, law enforcement sources told The Post.

Sources said the alleged rape took place after the woman was invited to sleep inside the suspect’s tent while he went to work. But she soon awoke to the suspect allegedly taking off her clothes — and refusing to heed her pleas to stop. She was then allegedly raped, the sources said.

Iketubosin has been working and demonstrating at Zuccotti Park for more than a week.
