The Detroit-Windsor Tunnel was closed for several hours early Sunday morning after police found a suspicious package inside a bus. It apparently turned out to be a hoax.
According to Detroit police, the driver of an empty Greyhound bus noticed a suspicious suitcase on board.
A scan of the suitcase revealed two pipes with wires sticking out of them, which prompted Detroit police to call in the bomb squad.
Further investigation of the package found it to be harmless.
