DALLAS (CBSDFW.COM) – A man who authorities said was dating a 14-year-old girl while posing as a Dallas ISD high school student has pled guilty to third-degree indecency and records tampering.

Sidney Gilstrap-Portley, 26, was arrested last year after authorities found that he was enrolled at Hillcrest High School under the guise of 17-year-old Rashun Richardson. He also played for the school’s basketball team.

On Tuesday, the man pled guilty to both charges and received probation as penalty. It was also ruled that he must register as a sex offender for 10 years.

After the guilty plea, Gilstrap-Portley said very little about his admission or why he had decided to pose as a teenager at the high school. He offered a quick apology after his lawyer spoke for him.
