Law enforcement officers were looking for signs of two Clinton Correctional Facility escapees in farms and fields about 40 miles south of the prison.

State police were being assisted by other agencies Tuesday afternoon in Willsboro in Essex County after two suspicious people reportedly were seen in the area.

Local officials said there may have been an unusual incident earlier in the day but they were unable to provide specific information.

Authorities have said inmates David Sweat and Richard Matt were discovered missing from the prison around 5:30 Saturday morning.

Time Warner Cable News reported a law enforcement source said the search in Willsboro began after a "credible tip" was received from a civilian who believed the suspicious people may have been the escapees.

State police investigators have been tracking down hundreds of leads in an effort to find Sweat and Matt.

A tip line has been established for people with information about the escapees. The number is 1-800-GIVE-TIP.
