AUSTIN, TX - A fight between two rival gangs left one inmate dead and at least three others injured with stab wounds at a northeast Texas prison, officials said.

Prison authorities said Augustin Amador, 34, died in a hallway at the Telford Unit in New Boston after receiving 23 stab wounds.Officials said the incident was isolated and quickly controlled. It was the first killing this year in a Texas prison after two were reported last year.

"Any type of gang activity is something we closely monitor," said Michelle Lyons, a spokeswoman for the Texas Department of Criminal Justice. "This (incident) is why we are doing that."

According to officials, Amador and four other members of the Tri-City Bombers were attacked by six members of the Texas Chicano Brotherhood as they were being escorted back to their cellblock after lunch. The Tri-City Bombers is a gang based in far South Texas in communities west of Harlingen.

The assailants were armed with prison-made knives, six of which were found in the hallway after the fight. The assailants were arrested and were being questioned, officials said.

Correctional officers deployed three canisters of pepper gas and stopped the fight within minutes, officials said. The three injured inmates were treated at the scene. Other inmates were ordered to their cells and the unit remained on lockdown late Monday, which is standard procedure after a fight, officials said.

The 2,800-bed Telford Unit, which is located in Bowie County about 145 miles northeast of Dallas, was one of 13 Texas prisons on partial lockdown Monday, officials said. In at least eight cases, gang tensions and disturbances prompted the lockdowns.

Officials said Amador came to prison from Hidalgo County in 1997 to serve a 16-year sentence for murder and burglary. He was also serving a separate sentence of undetermined length from Jackson County for possession of marijuana and possession with intent to deliver cocaine.
