San Bruno police have identified two individuals who fired gunshots at the Tanforan Mall Tuesday.
Police identified 18-year-old Deandre Lejon Gantt from San Francisco and a 16-year-old also from San Francisco.
The two suspects were taken into custody and booked at the San Mateo County Youth Services Center where they face charges related to the shooting.
On July 2, police in San Bruno responded to a shooting that left two teenage boys wounded at the Tanforan Mall.
In what police said was not a random shooting, one victim was in critical condition and the other was in serious condition, but both were stable, according to San Francisco General Hospital.
Police said they were searching for two suspects, one of whom may have fled on a BART train and made it across the bay to Oakland. The two gunmen reportedly had been shooting at each other.
"Evidence at the scene indicates that there were two groups of people who engaged in a dispute with each other on the second floor of the mall," police said in a statement released Wednesday. "This dispute escalated and one subject from each group began shooting at the other."
At about 4 p.m., BART closed down its San Bruno station after it received reports of an active shooter.
Later, BART shut down the 12th Street station in Oakland as police cleared trains in search of a possible suspect. Police said reports of a gun from the shooting being recovered were unsubstantiated. That station reopened about 5:30 p.m.
Video from the scene showed police officers swarm the Oakland station with guns drawn.
The San Bruno station remained closed for hours until it reopened just after 8 p.m.
Workers at the mall at 1150 El Camino Real said the mall was placed on lockdown, and police were asking the public to avoid the area.
Video posted to social media showed people running and walking out of the mall. Two additional people were reported injured in the evacuations, and they were treated and released, officials said.
A parking structure at the mall also was placed on lockdown, and people who parked there weren't able to get to their vehicles for hours.
