In the wake of Sunday's fatal double subway stabbing, Metropolitan Transportation Authority officials say they are working on almost doubling the number of functional cameras in subway stations.

In a statement issued Tuesday, MTA officials said that there are 2,270 operating cameras in the subway and that another 910 will be working by June.

Eventually, the MTA plans to have 4,313 working cameras in the subway system, and the agency says funding will come from its capital program.

"A lot of those cameras don't work and someday maybe we're going to get very badly hurt because of it," said one city straphanger.

The MTA says its top priority is the safety and security of its riders.

Meanwhile, police have posted fliers at Manhattan's Christopher Street station requesting help from the public.

Investigators believe the attacker or attackers got off a Brooklyn-bound 2 train at the station after stabbing three men during a fight, killing Darnell Morel, 24, and Ricardo Williams, 24.

MTA officials say the token booth on the southbound side of the station was closed last year because of budget cuts, meaning there were no station agents who might have caught a glimpse of the killer.

The Christopher Street Station does not have working security cameras.
