The call comes — as 4 MTA workers were attacked in some way on Thursday within a span of a couple of hours across the city. “TWU Local 100 is continuing its efforts to increase worker safety by demanding a greater police presence in the mass transit system,” said TWU 100 Stations Vice-President Robert Kelley. “The NYPD added hundreds of officers to the subway earlier this year – but that’s not enough. More officers in the subway would deter more crime and speed police response to emergencies – and Mayor de Blasio also should direct police to ride buses to help protect Bus Operators.”
