John Attanasio, former dean of the Dedman School of Law and current Judge William Hawley Atwell Chair of Constitutional Law and professor of law, was arrested Sunday morning on a prostitution charge, The Dallas Morning News reported Sunday evening.

Jail records show that Attanasio was booked into the Collin County jail Sunday and released later after posting $500 bond. He was arrested by the Texas Department of Public Safety for a Class B misdemeanor.

“I can confirm that John Attanasio is a full-time member of the SMU law school,” an SMU spokesperson said in a statement to The Dallas Morning News. “It would not be appropriate, however, for SMU to comment on matters that are being investigated by area police.”

Attanasio served as dean of Dedman School of Law from 1988 until 2013 when SMU declined to renew his contract. As dean of SMU, Attanasio raised over $115 million in gifts and pledges, increased the book value of the endowed by more than $30 million, and increased the median GPA and the average LSAT scores of the entering classes.

According to a Texas DPS spokesman, the arrest is part of an ongoing investigation. The Daily Campus will continue to provide updates as more information becomes available.
