ADVERTISEMENT Another man who was in the workshop at the time of the explosion was rushed to a hospital with severe burns, a police officer told Reuters. The workshop was destroyed and several cars parked outside caught fire. Police found several unexploded army issue rocket-propelled grenades in the workshop. They believe the ammunition had been brought there by scavengers wanting to sell them as scrap metal, but they also are investigating a possible link to Rio's heavily armed drug gangs who often raid military bases.
