Deep inside city jails, top cops keep a watchful eye out for terror
Brooklyn-born terror suspect Jose Padilla converted to Islam in prison.

An elite group of correction officers, cops and federal agents is closely monitoring suspected radicals at city jails to prevent them from recruiting angry and isolated prisoners into their fold.
Authorities believe the jails, along with prisons across the nation, could become fertile recruiting grounds for homegrown jihadists who follow the teachings of Osama Bin Laden and other Islamic terrorists.

Aware of the great risk, city correction bosses created the specialized intelligence unit on Rikers Island to stop fanatics before they can indoctrinate others.

"We aggressively monitor all security risk groups," Martin Horn, who runs the city's Department of Correction, told the Daily News. "We have our own intelligence unit and we're always looking at inmate alliances."
