A massive fire that broke out Thursday morning in the heart of London's Tech district is now under control, according to the London Fire brigade.

The cause of the fire is still under investigation.

The fire, which broke out before 9 a.m, occurred in a six-storey building that's under demolition on Old Street, the fire department said.

"Crews worked hard to contain this blaze and to stop it from spreading. The main fire was concentrated around the building's central lift shaft. This created a chimney effect, which is why smoke could be seen for miles around during the early stages of the incident," Station Manager Gareth Cook said in a statement.

The blaze was under control by 10:15 a.m., after the first emergency calls started rolling in around 8:44 a.m. Eight fire engines and 58 firefighters were on the scene.
