A law enforcement official in New York, speaking on condition of anonymity, said the tightening of security was prompted by an informant's report of a plot to attack the subway system with bombs hidden in bags and possibly baby strollers.
"If I'm going to make a mistake, you can rest assured it is on the side of being cautious," Bloomberg said.
