Police found a bomb early Wednesday at the Tokyo home of Deputy Foreign Minister Hitoshi Tanaka, the key official for negotiations and policymaking on North Korea, after being alerted by news organizations that received suspicious calls, police officials said.
They found the device -- a cylindrical steel object containing a small heater and a pressured gas cylinder connected by lead wires to a small box with batteries and a timer -- in the ground floor carport of Tanaka's home in Meguro Ward.
The timer was ticking, police said.
