The burning fuel forced manhole covers to blow, according to fire spokesperson Maurice Luque.
Plainclothes policemen formed a human chain to rescue a 5-year-old boy who fell into a 10-feet deep catch basin in the Northwest Side, but then became embroiled in an altercation with the boy's family that led to the arrest of three people, one of them disabled by a police taser, according to the Sun-Times.
The boy, Alex Banuelos, fell into the hole on private property; the boy's mother flagged the police down. The officers formed a human chain, pulled Alex up, and called paramedics.
But while paramedics were attempting to aid the child the boy's uncle, 17, allegedly began to argue with the police officers, eventually punching one in the chest. Another man became agitated, forcing police to taser and subdue him.
In all, three men were charged with misdemeanors, according to the Sun-Times.
The catch basin cover, which collapsed when the boy stepped on it, has been replaced with a more sturdy aluminum plate.
