Officers on patrol observed a suspect throw a large fire extinguisher from the elevated station platform down to the street below. Although no one was injured, the area was crowded and the suspect's actions endangered other people at the station. The suspect was arrested and booked for two outstanding warrants ($10,000 for burglary and $10,000 for battery), assault with a deadly weapon and tampering with fire protection equipment and issued a prohibition order from all BART stations.
