Faith leaders got a lesson from the FBI in New Haven Monday about what to do in the event of a threat.

The Anti-Defamation League announced on Monday that Jewish threats have tripled over the last year in Connecticut.

In the past few months, the Jewish Community Center and the Islamic Center in Woodbridge have received threats, racist fliers have appeared in Norwalk and swastikas were found in Danbury. 

The two religious groups say they are putting up a united front against hate speech.

Last Friday, authorities filed federal charges against an Israeli-American teen who could be behind almost 250 threatening phone calls.

Connecticut's U.S. Attorney Deidre Daly assured faith leaders that they will prosecute these cases.
