A male suspect became involved in a dispute with a taxi driver at the BART station. The taxi driver left with the male and then returned because the male suspect did not have enough money to pay his fare. The dispute continued in the taxi zone. The male punched and then attempted to cut the driver with a knife. Colma and Broadmoor police were on-scene almost immediately and arrested the male suspect. Broadmoor police requested to take primary jurisdiction of the case and took custody of the male and will conduct follow-up investigation. The taxi driver was transported to the hospital for treatment of minor injuries.
