Moment rubbish truck explodes in a Chicago suburb

A rubbish truck suddenly exploded on a street in suburban Chicago.

The Arlington Heights Police Department has launched an investigation into the incident, stating that the working theory is an "uncontrolled combustion in a garbage truck hopper, igniting Compressed Natural Gas (CNG) tanks."

Two officers were injured and are recovering at home, while one firefighter, also caught in the blast, has returned to work.
