A fugitive ex-Occupy Wall Street protester was busted after the US Marshals Service found him hiding out on the streets of Hell’s Kitchen, The Post has learned.

Preston Laska, 23, was wanted on kiddie-porn charges in Wisconsin, which he fled after being convicted of similar charges.

The feds learned he was in the Big Apple after he was arrested for sleeping on the sidewalk and released before his fingerprints were confirmed.
