Molotov cocktail found near federal offices in Phila.

A Molotov cocktail was discovered yesterday afternoon in a garage near a Philadelphia office of the Department of Homeland Security and triggered an investigation by city police and federal authorities.

A bottle filled with diesel fuel was found just before 2 p.m. in the garage at Callowhill and 16th Streets. The garage is across Callowhill from Immigration and Customs Enforcement offices. Initial reports said a laptop computer and several anti-Israel books had been found with the device, near a generator.

A tipster called police after seeing a man with several full trash bags emerge from a garage storage closet. A bomb squad unit "rendered safe" the Molotov cocktail, said Lt. Frank Vanore, city police spokesman. Police were trying to identify the man seen with the bags and determine if he was linked to the incendiary device. - Sam Wood
