A cryptocurrency investor from Kentucky is suspected of torturing an Italian businessman with a chainsaw in a sadistic, weeks-long extortion attempt to gain the password for his accounts at a ritzy Manhattan apartment – before the captive made a daring escape, police sources said.

John Woeltz, 37, was arrested after the bloodied and bruised businessman – a 28 year-old man – broke out of the SoHo house of horrors Friday morning, ran to a police officer and said he’d been held prisoner for more than two weeks, the sources said.

Cops rushed to the luxurious Prince Street pad – which Woeltz was allegedly renting for roughly $30,000 to $40,000 a month – and discovered multiple Polaroid photos showing the businessman being tied up with electrical wire and tortured, including one of him bound to a chair with a gun pointed at his head, according to the sources.

Since being taken captive, the businessman had been bound with an electric cord, Tased while his feet were put in water, pistol-whipped, forced to take cocaine and threatened to have his limbs cut off with an electric chainsaw, the sources said.

The nightmare erupted from a dispute over cryptocurrency, in which the suspect allegedly tried to extort millions of dollars from the man by unleashing a litany of horrific tortures, according to sources.

The man was rushed to Bellevue Hospital for treatment, while cops arrested Woeltz, who was expected to face an assault charge, the sources said.

Woeltz was charged Friday night with two counts of second-degree assault, first-degree kidnapping, first-degree, first degree unlawful imprisonment and criminal possession of a weapon.
