One P.F. Chang's kitchen worker was stabbed to death Saturday, allegedly by another, at the restaurant in Peabody, Massachusetts.

Essex County District Attorney Jonathan Blodgett said 23-year-old Jaquan Huston used a knife to stab his coworker at the restaurant, located at the Northshore Mall.

Police responded just after 5:30 p.m. The victim, identified as 38-year-old Elivelton Dias of Salem, was rushed to Salem Hospital, where he was pronounced dead on arrival, Blodgett said.

Huston was arrested at his home in Salem. He is scheduled to be arraigned on murder charges in Peabody District Court Monday.

"This was an isolated incident," said Blodgett. "It's a very difficult, sad situation."

Other staff members and witnesses are being interviewed as the investigation continues.

P.F. Chang's later released a statement on the incident:

"Tonight we lost an employee in a tragic incident at our Peabody restaurant. Our thoughts and prayers are with the family and friends of our colleague. We will be mobilizing support to provide care to our colleague's family, as well as our fellow employees, during this difficult time. We are also cooperating with local law enforcement as they conduct their investigation."
