Local officials are believed to have named the attacker as Nikolas Cruz.
He was arrested without incident roughly a mile away from the site of the horrific Valentine’s Day massacre at Marjory Stoneman Douglas High School in Parkland.
The suspect was then taken to Broward Health North medical centre where he was treated and then released into police custody.
Now people who claim they knew the alleged attacker say he was banned from carrying a bag on the school campus.
The Sheriff said the suspect was armed with an AR-15 semi-automatic rifle.
“There were problems with him last year threatening students, and I guess he was asked to leave campus.”
A student interviewed after the massacre claimed the attacker had shown other classmates. pictures of guns he owned.
The student was expelled from the school for “disciplinary reasons”.
According to other students speaking to local media, other students “knew it was going to be him”.
One student said: “A lot of people were saying it was going to be him. A lot of kids threw jokes around saying that he was going to be the one to shoot up the school.
“It turns out that everyone predicted it. That’s crazy.”
Students described him as a troubled kid who was the subject of jokes from other kids.
Seventeen-year-old junior Matthew Walker said he was known to show off knives and guns on his social media accounts.
He said: “He was going class to class just shooting at random kids.
“Everything he posts [on social media] is about weapons. It’s sick.”
