MIAMI GARDENS, Fla. – Two teenagers were shot Thursday by an unknown assailant near a Miami Gardens high school, authorities said.

The shooting occurred late Thursday afternoon in a neighborhood near Miami Carol City Senior High School. Sky 10 was above the scene as a large police presence surrounded a nearby neighborhood.

Miami-Dade Fire Rescue said one of the teens was shot in the head, but the extent of the second victim's injuries were not released.

A representative with the school board said one of the victims sought help from a teacher, who they said assisted.

Both victims were airlifted from the school's football field to a Jackson Memorial Hospital, where their family members were seen arriving shortly after.

Police were spotted in the area with their guns drawn after the victims were transported, but it is unclear at this time whether there was a barricaded subject or if they were still searching for the gunman.

A Miami-Dade County school spokesman said the teens were not students at Miami Carol City Senior High School.

According to police, the shooting happened between 3:45 and 4 p.m., after all three of the schools were dismissed for the day. Night school and after-school activities were canceled at Miami Carol City Senior High School due to the shooting.

Still, the high school and two other schools -- Carol City Middle and Barbara Hawkins Elementary schools -- were placed on lockdown following the shooting. The lockdown was lifted just before 6 p.m.

Officials said 200 students in elementary school, 75 students in middle school and 400 students in high school were affected by the shooting.
