VERNON, CT (WFSB) -- The man at the center of a sex trafficking case is facing more charges.
Simon Hessler, 47, was charged with four counts of fourth-degree sex assault and four counts of risk of injury.
This is part of an ongoing investigation that began last year.
Hessler, a former Ellington volunteer ambulance worker and hotel owner, is accused of running a sex dungeon.
He already faces a number of charges, including human trafficking, second-degree sexual assault, promotion of child pornography and more.
It was a coworker who first called police to complain about prostitution at Hessler's hotel.
Last month, investigators dug through Hessler's Vernon-New England Hospitality Management business.
They believe he was negotiating the delivery of a young girl to his other business, the Baymont Inn and Suites in Manchester.
Police said they arrested him when he tried to pay an undercover officer for the delivery of the victim.
During a search warrant execution, investigators said they found the sex dungeon and related paraphernalia at the Vernon business, which included multiple beds, whips, chains and handcuffs.
"Sometimes in the morning, I catch myself looking at it and thinking about what happened and what I found out," said Brittany Dyer.
Brittany Dyer, who lives two doors down remembers last November when police searched the building.
"Ever since then, I lock my doors every night," Dyer said.
Hessler has been in jail since last November, facing ore than ten felonies and a possible life sentence.
State police did not officer details about the newest charges.
Hessler's new charges add $75,000 to his bond amount, which now totals more than $1 million.
