Officers were called to the restaurant at about 2:20 p.m. Witnesses said two brothers, who work in the kitchen, got into an argument. Armando Urbal, 31, apparently told his younger brother to mop the floor, and the younger one became upset and attacked him with a knife, according to police reports.

The older brother struggled and received only some minor cuts to his arms, police said.

Luis Alberto Mojica, 17, of Martha Court, was charged with first- and second-degree assault and disorderly conduct, according to online court records. He was charged as an adult due to the seriousness of the offenses, police said.

Neither man spoke much English and police officers called in a Hispanic liaison to translate the victim's statement. The victim told the interpreter this has happened before.

"The victim says his brother does have an anger problem," said Officer Hal Dalton, a city Police Department spokesman. "It's usually not this bad. But he has reacted violently before to directions and instructions."

Fights in restaurants are a concern because of the easy access to weapons, he said.

"There are so many weapons at your disposal in a kitchen," he said.

The knife used in the fight was a large butcher knife from the kitchen, according to reports. No one else was injured in the fight.

Monica Meza, who works at the restaurant, said the brothers frequently argued but it had never before became violent.

"It was just about two brothers fighting, that's all," she said.
