ROWLETT (CBSDFW.COM) – A teacher from the Rockwall Independent School District is out of jail on Thursday after he was arrested and accused of sexually assaulting a teenager. Police in Rowlett have been investigating this case for months, but did not take James Smith into custody until Wednesday night.

Smith walked into the police department late Wednesday and turned himself in to detectives. He then posted a $50,000 bond overnight. CBS 11 News was at the department when the 50-year-old man surrendered on a charge of sexual assault of a child, however, he did not answer any questions.

The accused teacher again refused to comment when called on Thursday morning.

Authorities stated that the incident happened last year in Rowlett, and involved a teenage girl under 17 years old. They are not releasing any more specifics about the case, but police and Rockwall ISD officials stressed that these allegations do not involve a district student, school or property.

Smith is a teacher at Utley Middle School in the Rockwall ISD. According to his school biography, he has been with the district for seven years and has a 24-year career in education. He is also a boys athletics coach. When police notified the district about the allegations on Tuesday, Smith was immediately placed on leave.

Detectives started looking into this case back in November, when the accusation first surfaced, but said that they waited to tell the Rockwall ISD so that they could fully investigate the allegation.
