Authorities are searching for two convicted murderers who used power tools to escape from a maximum-security New York prison in a "Shawshank Redemption"-style breakout.

Gov. Andrew Cuomo says Richard Matt and David Sweat broke out of the Clinton Correctional Facility in an "elaborate, sophisticated operation" that involved shimmying through a steam pipe.

The men were reported missing from their beds at about 5:30 a.m. Saturday.

Roadblocks were set up in the area of the prison, about 20 miles from the Canadian border. Bloodhounds and helicopters were being used to track down the men.

A $100,000 reward has been posted for information leading to their capture.
