The New York Police Department is taking extra precautions at hotels across the city, following a twin hotel bombing in Jakarta, Indonesia on Friday.

Although there is no specific threat in the city, NYPD officials say critical response vehicles and members of the counterterrorism bureau have been assigned to the Marriott, Ritz-Carlton and dozens of other hotels.

“There’s no information of a similar threat to New York, but it’s out standard practice now to take such precautions and to brief security directors in New York of what we learn,” said Police Commissioner Ray Kelly in a statement.

A teleconference on hotel security was also held in Downtown Manhattan Friday with a lieutenant on the scene.

Police are also communicating with security managers at hotels, who they say, are a first line of defense.

“We live in a dangerous world. We tell our folks to be alert at all times,” said Kelly. “We’re looking at this event to see if there’s anything we can learn, anything we can gleam from this that will help us better protect the city and the country.”

“The NYPD has those details necessary to provide those training resources necessary to its membership and private sector colleagues, in this case in then hotel industry, such that they can understand exactly what they can do,” explained John Colgan of the security company Secure Watch 24.

Meanwhile, investigators in Indonesia say the bombers who attacked the Ritz Carlton and Marriott hotels posed as guests and checked in with explosives, evading metal detectors and security guards.

The explosions killed at least eight people and wounded more than 50 others.

At least eight Americans are among the injured.

Police say the attackers smuggled explosives into the Marriott in Jakarta and assembled the bombs in rooms they had occupied since Wednesday.

A bomb went off at the Ritz Carlton next door two minutes after the Marriott blast.

Meanwhile, hundreds of postings have turned up on a Web site used by Indonesian jihadists praising the attacks.

Investigators suspect an al-Qaeda-linked group that’s been blamed for other deadly attacks.

It has been almost four years since the suicide bomb attacks in the Indonesian island of Bali.
