Washington: A microwave oven caused momentary disruption and a detour to a marathon in Pittsburgh, and a bomb squad had to be brought in to confirm it had no explosive.
The Pittsburgh Marathon on Sunday drew the full-scale response of a police team after a passer-by said an oven kept near a sidewalk contained a pipe bomb.
Police launched an investigation to know the oven came up on the sidewalk, just a couple of blocks from the marathon`s finish line.
"Based on what was seen inside and the preliminary findings of the bomb techs, we don`t believe there were any explosive materials," acting police Kevin Kraus was quoted as saying by the Pittsburgh Post Gazette on Monday.
Police shut down access to a few areas, and switched the last portion of the marathon to a different route.
The bomb scare came a day after a vehicle containing several explosive devices was found in New York City`s Times Square.
