Police reopened Gallivan Boulevard in Dorchester Tuesday afternoon after closing the street while searching the neighborhood for a man suspected of firing multiple gunshots in the area.
The search, which began around 12:19 p.m., was largely completed around 1:35 p.m., but police surrounded a house on Alicia Road shortly before 2 p.m.
There were no reports of anyone being shot, Boston Police Sergeant Detective John Boyle said.
Patrick McCorry said he was home watching a movie when he heard about seven or eight shots.
“I’ve been in the military, I know the sound of a gunshot,” McCorry said. “So I knew right away what it was ... Like a bang, bang, bang, bang, bang.”
He said he feared for the students at the nearby Henderson Upper School, which went into safe mode for about an hour.
“That was my biggest thought,” he said.
As of 3:15 p.m. Tuesday, the suspected shooter remained at large, police said.
Gallivan Boulevard was closed at its intersection with Dorchester Avenue, Washington Street and other roads in the neighborhood while police in uniform and in plainclothes accompanied by a K-9 searched for the suspect, who was believed to be armed. A drone was also used in the search.
A Boston Fire Department station was in the area of the shots fired incident and Boston Firefighters Local 718 thanked law enforcement agencies for their response.
“Earlier this afternoon at approximately 12:15 our members assigned to Ladder 6 were in the direct vicinity of a shots fired incident in Dorchester. We are relieved to confirm that none of our members or apparatus were struck by the gunfire and there were no other injuries,” the union said. “Local 718 is grateful to our public safety partners at the Boston Police and Massachusetts State Police who quickly responded to the scene and ensured the safety of our members and the public.”
State Police, which has jurisdiction over Gallivan Boulevard, said on Twitter around 1:20 p.m. that the road had reopened.
The police activity caused delays on the MBTA’s Red Line trolley. Regular service resumed shortly before 1:30 p.m., the MBTA said.
