Correction officer Jeff Bromley, who is accused of having an illegal sexual relationship with a 28-year-old inmate at the Niantic women’s prison, brought her snacks and small gifts, took photographs of her with his cellphone and had sex with her in the basement and laundry room of her housing unit, according to a court document.

Bromley, 46, who was charged by state police earlier this month with second-degree sexual assault, was arraigned Thursday in New London Superior Court. Judge Omar A. Williams transferred the case to the court where major crimes are tried and continued it to March 4. Bromley is free on a $15,000 bond and has retained attorney David R. Kritzman.

Bromley, who has worked for the Department of Correction since 1999, is currently on administrative leave, according to a department spokesman.

According to an arrest warrant affidavit, state police were called to the Janet S. York Correctional Institution on Oct. 31, 2014, after the inmate made sexual allegations about three correction officers. To date, Bromley is the only person charged in the case, but state police said the investigation is continuing. Officers involved in the case were transferred to another state facility, according to the affidavit, and the alleged victim was placed in a segregated housing unit.

The woman, a sentenced inmate, told troopers she had sexual contact with three different correction officers in the prison’s Davis Building between August and October 2014 and was concerned that one of them had impregnated her, according to the warrant. She was examined in the prison’s medical unit, and pregnancy tests were negative.

The woman described Bromley’s body in graphic detail, with specific information about scars and tattoos and his genitalia, according to the affidavit. She said Bromley brought her ice cream, sushi and chocolate-covered cranberries. She said he took pictures of her with a cellphone and recorded a video of one of their sex acts. She said she wrote him approximately 30 to 40 letters on lined paper and that he told her he wanted to have sex again after she was released from prison.

The woman provided detectives with an accurate description of the basement, a space that is off limits to inmates, where she alleges she had sex with Bromley, and led them to the laundry room where they seized the peach-scented air freshener she said he had given her. The investigators obtained a search warrant for Bromley’s cellphone and letters sent by the alleged victim.

When they served the search warrant at Bromley’s home in Willimantic, he stated he wished to invoke his Fifth Amendment right to remain silent and contacted his attorney, according to the affidavit.
