Former sophomore basketball guard Martez Walker was charged with criminal trespassing on the UT campus Tuesday, according to a Travis County affidavit.

After Walker was charged with assault with injury in the San Jacinto Residence Hall last week, he received a letter from Dean of Students Soncia Reagins-Lilly prohibiting him from returning to the dorm without permission from the vice president of student affairs, according to the affidavit.

The letter, which went into effect Thursday, stated, "If you violate the terms of this letter, you will be arrested for criminal trespass, in accordance with Texas' Criminal Trespass statute."

Despite this order, Travis County records show he was seen entering the dormitory at 10:08 a.m. Monday.  Once an officer arrived at the dorm, Walker was taken into custody for criminal trespass and transported to the Travis County Jail.

While UTPD said the incident happened on Monday, the affadavit reports Walker was booked on Tuesday.

Head coach Rick Barnes suspended Walker from the team indefinitely last Friday after the alleged assault. 

If convicted, Walker faces a Class A misdemeanor charge, which carries a penalty of up to $4,000 and/or a year in jail.
