A former IT guy who worked for Jeffrey Epstein said he quit over concerns about the hordes of topless underage women who frequented the wealthy sex offender’s private Caribbean island, according to a new report.

Steve Scully got an inside look into Epstein’s disturbing lifestyle and bizarre behavior — which included wearing Lacoste shirts just once and keeping “stacks” of extreme martial arts DVDs — while working for him for six years, beginning in 1999.

The computer whiz told ABC News there was no shortage of nude pictures of women at Epstein’s compound on an island near St. Thomas, dubbed Little St. James.

“There were photos of topless women everywhere,” Scully, 69, told the network. “On his desk, in his office, in his bedroom.”

A giant framed photo of a topless woman also hung prominently in the gym where Epstein worked out, the dad of three girls recalled.

Scully, who at the time ran a telecommunications business on St. Thomas, was hired by Epstein to set up a communications network on his exclusive 72-acre island.

He estimated he visited Little St. James 100 times and did about $400,000 worth of business with Epstein, who wanted phone or internet access everywhere on the island, including in a secret cove he called “the grotto.”

“He was the most intense person I ever met,” Scully said, noting that because Epstein worked in trading, he “never wanted a call to drop.”

Scully recalled seeing a rotation of young girls accompanying Epstein on the island, riding ATVs or sunbathing topless at pools and beaches — without any parental supervision.

“They couldn’t have been more than 15 or 16 years old,” he said.

Scully said he now regrets sticking around on Epstein’s payroll for so long.

“The truth is, I was there for six years. I really started seeing things weren’t normal in the first year. And I started … I wear shame and guilt,” he said. “Because you know what? When you allow money to dictate your moral consciousness, you’ve lost all idea of moral consciousness. It’s not about the money. It can’t be.”

Scully remembered other details from his time on Little St. James — which he said Epstein once wanted to rename Little St. Jeff.

“He had stacks and stacks of extreme martial arts DVDs,” said Scully, who hasn’t spoken to the financier in more than a decade.

And then there was the storage room on the island stocked with “stacks and stacks of brand new Lacoste white polo shirts, all size medium.” Scully said he was told the clothes were for “Mr. Epstein” and that an employee said the 66-year-old only wore a shirt once before it was turned into rags for the housekeeping staff.

Lawyers for Epstein did not immediately comment to ABC about Scully’s claims.

He is charged with sex-trafficking dozens of underage girls and forcing them to perform nude massages and other sex acts on him from at least 2002 to 2005.
