WORCESTER, Mass. — Authorities say a woman was fatally stabbed at a restaurant in Worcester and a suspect from New Hampshire is in police custody.

Worcester police said the 31-year-old victim, whose name wasn’t released, was attacked Wednesday night at O’Connor’s Restaurant. A restaurant patron from Connecticut who rushed to help the woman also was stabbed and suffered injuries not considered life-threatening, according to reports.

Police arrested 28-year-old Carlos Asencio, of Derry, after others at the restaurant overpowered him and held him until officers arrived.

The Telegram & Gazette reported that Asencio had previously dated the woman. He was expected to be arraigned Friday on charges of murder, armed assault with intent to murder, assault and battery with a dangerous weapon, and other offenses.

It was unclear whether Asencio had a lawyer authorized to speak on his behalf.
