One of three men accused of stabbing two brothers from Lawrence used a phony name at his arrest outside a downtown nightclub early yesterday morning, Suffolk County District Attorney Daniel F. Conley said.

SANTIAGO HERNAIZ (D.O.B. 1/8/81) of Roxbury used the surname “Hernandez” when arrested by Boston Police outside the nightclub Felt shortly after 1:30 Sunday morning. His true name was revealed this morning prior to his Boston Municipal Court arraignment on charges of assault and battery with a dangerous weapon.

Assistant District Attorney Spencer Lord recommended that Hernaiz be held on $25,000 cash bail; Judge Sally Kelly set bail at $2,500.

Hernaiz’s co-defendants, LUIS A. ALICEA (D.O.B. 12/31/86) of Hyde Park and WILLIAM R. SANJURJO, Jr. (D.O.B. 7/22/88) of Dorchester, posted bail following their arrests and are expected in court later this week.

Shortly after 1:30 Sunday morning, Boston Police responded to the area of 533 Washington St. for a report of a stabbing. The officers were met by four brothers, two of whom had sustained stab wounds. One victim, age 31, was suffering from injuries to his abdomen and lower back and was transported to New England Medical Center; the other, age 33, was suffering from an injury to his chest and was transported to Massachusetts General Hospital. Both men are expected to survive.

The 31-year-old victim told officers that he and his brothers had scuffled with the three defendants inside the club before being escorted from the building. He also told the officers that the defendants then assaulted him and the second victim outside the club, identifying Sanjurjo as the one who stabbed them. An uninjured brother identified the same man as having wielded a knife during the incident.

The officers recovered a knife outside the building and took the defendants into custody. They later seized clothing from the victims and suspects.

Hernaiz was represented by attorney Steven Kim. He will return to court on Aug. 16.
