Sept. 12 (Bloomberg) -- The New York City Police Department will keep additional security measures such as vehicle checkpoints and increased bag checks at subway stations in place through the evening, a spokesman said.
The department will reassess security after the evening rush, Paul Browne, a spokesman for the NYPD, said in an e-mail. The measures were put into place last week after reports of a credible, uncorroborated threat that al-Qaeda might be plotting an assault in the city around the 10th anniversary of the 2001 terrorist attacks.
Concrete blocks were placed at intersections in Lower Manhattan to prevent traffic from getting close to the World Trade Center site where U.S. President Barack Obama and ex- President George W. Bush attended yesterday’s memorial service, and metal barricades were erected along streets to keep cars from stopping.
Other measures included extended shifts for police officers through today, stepped-up monitoring of bridges and tunnels, patrols outside places of worship and government buildings and bomb sweeps of public garages.
The Port Authority of New York and New Jersey is “still at a state of heightened security,” said Ron Marsico, a spokesman for the agency, which operates the city’s airports, the Holland and Lincoln tunnels, the George Washington Bridge and the PATH train system.
A decade ago yesterday, a group of men tied to the terrorist group hijacked four airliners, flying two into the World Trade Center towers in New York and a third into the Pentagon in Arlington, Virginia, and crashing a fourth in Shanksville, Pennsylvania, after passengers thwarted the hijackers. Almost 3,000 people were killed.
