A former Oklahoma teacher who is accused of engaging in inappropriate texts, also known as sexting, with a minor was arrested Tuesday in Texas.

Joseph Kolt Palmer, 27, was arrested by Kaufman County, Texas, deputies after a warrant was issued in connection with allegations he engaged in sexual communications with a 17-year-old girl, according to a news release.

The Yale Police Department asked for assistance from the Oklahoma State Bureau of Investigation, and agents collected text messages between Palmer and the student they said “explicitly described sexual acts.”

Palmer was hired by the Yale School District in August 2015.
