The 'heavily armed' shooter, named by police sources to DailyMail.com as former student Nicolas de Jesus Cruz, 19, entered Marjory Stoneman Douglas High School in Parkland, Florida, armed with what appears to be an assault rifle, and began shooting at just after 2pm.
Broward Sheriff confirmed that 'we have at least 14 victims' although he did not specify whether they had been injured or killed. Florida Senator Bill Nelson told Fox News there were 'many deaths'.
Sources told CBS at least seven people had been confirmed dead.
Students barricaded themselves into their classrooms, while others were seen running out of the building with their hands in their air as police and SWAT teams swarmed the school. Those fleeing the school, in single file, each threw their backpack into a large pile and huddled together under trees across the street.
At around 4pm, two hours after the shooter first opened fire, police and SWAT teams took him into custody. Police describe him as a student and a former member of the U.S. Army Junior Reserve Officers' Training Corps program.
Video shows him wearing a maroon or burgundy colored top as he was put in the back of a cruiser by half a dozens officers.
