An attempt to hide a drug in a car caused an explosion that peppered the walls of a petrol station with rocks of crack cocaine, Brazilian police said.
Police said a man and woman apparently tried to hide 11lbs of crack inside their car's natural gas fuel tank.
Police in Brasilia said that when they stopped to refuel their natural-gas powered car, the cylinder exploded.
Police said a 24-year-old woman suffered minor injuries. The 36-year-old man captured with her was also taken to a hospital for possible injuries.
