According to the Harris County District Attorney's Office, deputies had to restrain Pablo Castaneda, 17, who authorities charged with aggravated assault as an adult in connection with the alleged stabbing, after he reached for a weapon.
The district attorney's office said this happened while deputies led Castaneda from the 351st District Court to a holding area on Friday morning. Castaneda's alleged attempt at a gun resulted in a scuffle with deputies.
Records show that a judge had just lowered Castaneda's bond from $100,000 to $50,000 before the commotion.

The Houston Independent School District Police Department said the original stabbing happened on Sept. 18, and the victim, who got wrapped in a fight with the suspect, survived their injuries.
A Sterling student's mother shared a video of the stabbing with ABC13, showing her son standing a few feet from the attack.
"My baby is traumatized," she told Eyewitness News at the time.
The on-campus chaos was one of several school incidents that authorities said unfolded within a week in the Houston area.
Earlier this week, HISD said recent threats to campus have led to seven students arrested. In addition, the FBI's Houston field office said it logged more than 30 reports of threats since the beginning of the school year.
Eyewitness News also obtained data from the district attorney's office, showing 127 criminal charges filed against minors related to threats or the unlawful carry of weapons on campus between August 2023 and now. Eighty-five of them involved weapons.
