The Metropolitan Police Department (MPD) bomb disposal unit was called to JR Akihabara Station when a suspicious device was found in a restroom, which turned out to be a harmless motion sensor, it has been learned.
According to the Manseibashi Police Station, it received a call on April 23 from the station staff that "a circuit board with batteries is taped in a bathroom." An MPD bomb disposal unit was then dispatched to the station and found a 15-centimeter by 12-centimeter plastic case with a battery and a motor below the baggage shelf in the unisex multipurpose toilet near the station's Showa-dori Ave. ticket gates.
Upon inspection by the bomb disposal unit, it was judged to be a sensor to open and close the lid of a trashcan that had been removed. Police are investigating the incident as malicious mischief.
