A mysterious bomber is targeting police establishments in Sapporo, on Japan’s northern island of Hokkaido. After five gas cylinder explosions were reported in the parking lot of the Kita Ward police station, a police dorm and other commercial establishments nearby since January, a letter sent to a TV station announced that the next explosive would hit a koban, or police box.
In all the bombing incidents, it has been discovered that the areas are all within a 6 kilometer circular area of Kita Ward. Though warning letters have been sent to a newspaper and the Kita Ward police station in February, this is the first time a letter has been addressed to a male newscaster at the Hokkaido Cultural Broadcasting station. Authorities investigating the case believe the letters are legitimate because of details included, which “could only be known by someone involved in the case.” The recent warning letter also mentioned complaints against the police in Kita Ward and mentioned a koban in the capital as the “next target.”
Authorities suspect only one person could be behind the bombing incidents, as some evidence found in four of the five locations are the same. Pink gel “firelighters” near the gas cylinders and cooking briquettes are among those found. The warning letters, mailed in envelopes from the same company, also complain of the same police officer. While no one was hurt in the recent dorm explosion, some civilians were hurt when a gas cylinder in commercial facilities went off.
