This is the dramatic moment students chase a teenage gunman through their school after he allegedly opened fire and tried to target a teacher.
Terrified pupils and staff barricaded themselves inside classrooms after the 17 year old began firing in the playground as lessons started.
Officials said the teenager then tried to force his way into the headteacher’s office.

Footage later showed other students running after him through the school grounds.
The teenager then apparently turned the weapon on himself and was rushed to hospital in a critical condition.
The terrifying incident unfolded at the Gabriel García Márquez Educational Institution in Medellín, Colombia, on Wednesday (9 September), as reported by Need To Know.
City officials identified the suspect as Jhoan Sebastián Ovalle, a 10th-grade pupil who had reportedly been ordered to study from home a week earlier.
The school has around 1,000 pupils and panicked parents rushed to the gates after receiving calls from their children.
Mayor Federico Gutiérrez said: “Unfortunately a very serious situation occurred in an educational institution in Medellín.
“A 17-year-old entered the school with a lower-lethality weapon, fired several shots to intimidate people and later injured himself.
“He was taken to a medical centre.
“We are at the school with the authorities, checking exactly what happened.”
Security secretary Manuel Villa Mejía said the teenager entered the school by climbing over a wall.
He said: “Teachers and students, seeing what was happening, took shelter in the classrooms and closed the doors.
“This student then tried to attack and tried to force his way into the headteacher’s office.”
A teacher who is thought to have been the intended target was not at the school at the time.
The teenager was taken to Sagrado Corazón Clinic for treatment.
In a bizarre twist, two men aged 37 and 46 allegedly later entered the school and removed the weapon.
Investigators tracked them using CCTV and both were arrested.
Local media identified them as John Jairo Lora Sánchez and Wilson Alberto Rodas Lenis.
They are suspected of links to a criminal group in the area and face allegations of using a minor in crime and illegal possession of a firearm.
Police chief Brigadier General Henry Yesid Bello Cubides said investigators were collecting spent rounds, blood traces and witness statements.
Villa Mejía said the teenager had displayed “aggressive and violent behaviour” since last year and had received psychosocial support following emotional crises.
A mental health alert known as the “golden code” had also previously been triggered, although officials said the teenager later indicated he no longer wanted support.
Education secretary Carolina Franco said there had been no previous report of a serious incident beyond “coexistence problems”.
Childhood and adolescence police are assessing the next legal steps.
Investigators are now trying to establish how the teenager obtained the weapon and whether any adults were involved in the attack.
