NEW YORK - New York City police say they've blown up the second device found blocks away from where a bomb exploded in Manhattan.

The New York Police Department says the controlled detonation took place at a police facility in the Bronx on Sunday evening. They said the device has been rendered safe and that a forensic examination of the device will be conducted at the FBI Laboratory at Quantico, Virginia.

The second device was discovered Saturday night by state troopers after a bomb exploded in Manhattan's Chelsea neighborhood. Twenty-nine people were injured in that blast. They've all since been released from hospitals.

The second device was described by a law enforcement official as a pressure-cooker with wires and a cellphone attached to it. It was taken from the scene by a bomb removal robot.
