After a large fireball ignited near Elephant and Castle Railway Station on Monday, billowing clouds of plumes of black smoke over south London, a heroic police officer was seen rescuing two young children.

The moment the fire broke out of a building in arches directly underneath the station, extraordinary footage was taken. With the burning structure in the background, a brave police officer was seen saving the two children, one in each arm, to safety.

Twitter users praised the unnamed cop and demanded that the government recognize him for his courage. One Twitter user said, “Thank you for your service.”

“Policing is more than dealing with crime, it’s much more than that. #Hero,” another tweeted.

At 1.43 p.m. on Monday, June 28, the fire department got 50 notifications of a blaze in a nearby garage. Three business buildings beneath the railway arches were entirely ablaze, as were four automobiles and a phone box near Elephant and Castle station. According to the London Fire Brigade (LFB), ten firetrucks and over 100 firemen were battling the incident at its peak.

“I heard the explosion at first and then smoke from the mainline station,” said Daniel Pharaoh, 30, who lives in the neighborhood. “Then I heard all the fire engines turn up about 20 minutes later.”

The fire at Elephant and Castle station was declared ‘under control’ soon before 4 p.m., but LFB teams would stay on the site “for the next few hours to dampen down the scene.” Six injured individuals were treated at the scene, and one was transported to the hospital.

Street blocks remain in effect, and residents in the nearby area were recommended to have their windows locked by the London Ambulance Service.

The blaze started near the Elephant and Castle shopping mall, which was being razed to make way for a new high-rise building. At this time, the reason of the explosion is unidentified. The fire was “not believed to be terror-related,” according to the London Metropolitan Police.

A citizen and a cop were treated for respiratory failure of smoke, according to London Mayor Sadiq Khan. “My thoughts are with all those affected by the very serious fire in Elephant and Castle. I am in close contact with the Fire Commissioner,” he stated.

Dozens of people are waiting to be let inside the buildings. In the meantime, the Imperial War Museum had established a ‘respite centre.’ “Where the fire was—it’s potentially still a risk, it might be gas bottles, and it can take hours and hours to cool down,” a police officer aiding locals said.

“We are aware of the serious incident at Elephant and Castle this afternoon, which we understand originated in a railway arch unit adjacent to, but not forming part of, our development site,” said a spokesman for Elephant and Castle Town Centre.
