A Trumbull man police say worked as a tumbling coach in Fairfield has been charged with having a sexual relationship with an underage student.

Victor Marella, 24, of Stonewall Lane, has been charged with second-degree sexual assault, for allegedly having sex with a 14 year-old student in his Trumbull home last December. Marella was working as a tumbling coach at Sportsplex in Fairfield, police said.

"According to the victim, Mr. Marella was her tumbling coach and  he had taken her to his home where she was taken advantage of," police said. "Search warrants and a witness corroborated details in the victim’s complaint and the arrest warrant was obtained."

The case was brought to Trumbull Police by Fairfield Police, who contacted Trumbull last January to say they were investigating the case, after the victim had reported it to them.

Marella turned himself in on a warrant Nov. 22. Police said he was charged with second-degree sexual assault and risk of injury to a minor. His bond was set at $50,000, which he posted, and he will appear in court Dec. 2.
