The Oklahoma State Bureau of Investigation has issued an arrest warrant for a former Yale School teacher. 

Joseph Kolt Palmer, 27, is wanted for lewd acts by engaging in sexual communication with a minor by use of technology, according to an OSBI news release. 

In May, Yale Police Chief Phillip Kelly requested OSBI special agents to investigate an allegation that Palmer was having a relationship with a 17-year-old female student at the school, the OSBI states.

Special agents said they collected text messages sent between Palmer and the student, and that the messages explicitly described sexual acts.

The felony is punishable by up to 10 years in prison, up to a $10,000 fine or both.

Palmer was hired by the Yale School District in August 2015 as a full-time math teacher and coach.
