Josh Callazo, 20, was arrested in Garza County late Thursday night for a 2nd degree felony charge of aggravated assault with a deadly weapon.
Callazo is accused of throwing a hammer at Seraphin Lopez, 19, of Post on Wednesday. Lopez suffered life-threatening injuries from the incident and remains in serious condition at University Medical Center in Lubbock.
Lopez and the suspect got into the altercation after one of the suspect's family members was involved with a separate fight with Lopez, according to the Garza County Sheriff's Office.
Callazo was arrested without incident, and arraignment and bond is to be set Friday in Garza County
