An 18-year-old man was under arrest after two other men were stabbed early Saturday in the parking lot of the Hess gas station on Old Colony Avenue in South Boston, police said.
Police received a 911 call about the attack at 3:30 a.m., said Officer Neva Coakley, a department spokeswoman. Witnesses told police the stabbings occurred during an altercation among five to six men, she said.
The attack left a 33-year-old Quincy man hospitalized with life-threatening injuries at Boston Medical Center, Coakley said.
The second victim, a 26-year-old Waltham man, sustained serious injuries and was taken to Massachusetts General Hospital, she said. Coakley said she did not have information about the weapon used in the attack.
Dominic A. Bazzinotti of South Boston was arrested in connection with the stabbings, while a second man was identified by officers and released, Coakley said.
She said she did not know what charges Bazzinotti faces.
After arriving at the scene, officers obtained a description from witnesses of two people who had fled the parking lot.
Bazzinotti and the second man were stopped by officers at the corner of Dorchester and Rogers streets after a brief foot chase, Coakley said.
Officers continued to investigate Saturday afternoon, and could be seen walking on both sides of Old Colony Avenue.
Bazzinotti is scheduled to be arraigned Monday in South Boston District Court.
