ODESSA - An Odessa teacher remains behind bars. He's facing sex charges involving a student.
The teacher worked at Bonham Junior High and some parents told NewsWest 9, they received messages from the school about his arrest.
Bryan Berta is a 9th grade geography teacher.
He was arrested on Monday on charges of sexual assault but bailed out that night.
On Wednesday, he was re-arrested additional charges of having an improper relationship with a student.
Right now, he's sitting in the Andrews County Jail on a $90,000 bond.
We're told Berta, who has worked for the school district for six years, resigned from his job.
Since it's a sensitive issue, no more information is being released right now.
Officials are still investigating.
