Two Chelsea men were arrested with weapons after a fight in the Mystic Avenue housing projects July 22, police said.

Winder Portillo, 17, gave Somerville Housing Authority officers a false name after they found him with a large kitchen knife and a screw driver, police said.

Three of the men involved in the fight fled but police stopped Portillo as Nelson Flores, 20, drove away, police said.

Flores allegedly admitted he did not have a driver’s license after giving investigators “several different names and dates of birth,” police said.

Portillo was arrested and charged with possession of a dangerous weapon, furnishing a false name and outstanding warrants. Flores was arrested and charged with unlicensed operation of a motor vehicle and an outstanding warrant.
