ARMONK, N.Y. — Authorities say no explosives were found on board two planes at a suburban New York airport after a phone tip prompted a search.

A Westchester County Airport spokesman says a caller told officials he overheard two men talking about explosives aboard a flight to Atlanta on Friday at 7 p.m. As a precaution, police searched two Atlanta-bound planes with bomb-sniffing dogs and re-screened all luggage.

No explosives were found.

The flights were delayed for about two hours and took off at about 9:30 p.m. Police are investigating the phone tip.
