BRIDGEPORT, Conn. -- A Connecticut special education teacher charged in the sexual assault of a student has resigned from her position.

The Connecticut Post reports Central High School officials sent a statement Wednesday saying Laura Ramos submitted a letter of resignation as termination proceedings by the school district were underway. The district placed her on administrative leave June 9.

Ramos was charged Tuesday with second-degree sexual assault after police say she engaged in a sexual relationship with an 18-year-old student in the special education program.

According to an arrest warrant, another student brought the alleged relationship to light two weeks ago. The witness said he also received text messages from Ramos containing sexual content and allowed police to take photos of the messages, CBS affiliate WFSB-TV reports.

Ramos initially denied having a relationship with the alleged victim before telling police she had a relationship with the victim from Dec. 23, 2016 to April 2017.

Her lawyer has previously said Ramos is "cloaked in the presumption of innocence."
