A fight broke out in a Tennessee courtroom between a fatal stabbing suspect and a testifying witness.

According to WRCB, the fight occurred during a preliminary hearing, involving Eric McCullough, who was a suspect in a fatal stabbing in July, and Antwon Lee, who was set to testify as a witness against him. Apparently, Lee attacked McCullough on Tuesday morning during the hearing, and the Hamilton County jail went on lock down.

The Chattanooga court room was also locked down for a while following the brawl.

McCullough is accused of stabbing Lee. However, Lee was also arrested after recovering from being stabbed on charges of violation of the sex offender registry.

WRCB reporter Dan Kennedy recorded the above video of the incident on his cell phone.
