(CNN) -- Two bartenders have been arrested in connection with the killing of the grandson of civil rights activist Malcolm X, according to the office of the Mexico City attorney general.
Prosecutor Rodolfo Fernando Rios Garza said the men work at a bar called The Palace Club where Malcolm Shabazz and three friends had drinks early Thursday.
An argument ensued when the staff said the bill was $1,200. Shabazz was beaten while another man was threatened and stripped of his belongings, Rios said.
Shabazz, 29, was transported to Balbuena General Hospital, where he died of his injuries later Thursday morning, police spokesman Octavio Campos said Friday. The attorney general's office said his injuries included brain trauma and several broken bones.
