New evidence obtained by BBC Africa Eye contradicts the official explanation for the cause of an explosion which killed 23 people and destroyed a girls boarding school in Lagos, Nigeria, earlier in the year.
The blast occurred in Soba, a residential neighbourhood of Lagos, on March 15th, 2020, at about 8:56 am.
In its reaction to the incident at the time, the Nigerian National Petroleum Corporation (NNPC) claimed the explosion occurred as a result of a truck that hit gas cylinders near one of its petroleum pipelines.
But new evidence indicates that the NNPC explanation for the cause of the blast, that decimated over 100,000 square metres of Lagos, is incorrect.
A new video evidence filmed at the explosion site, five minutes before the blast, shows a catastrophic leak of vaporised liquid at the exact location where the NNPC high-pressure petroleum pipeline runs beneath the ground through that area.
