Bomb-sniffing dog dies in US sports arena fall

An explosives-sniffing dog died after he fell more than 50 feet during a security sweep to prepare for a US professional basketball game.

Mikey, a four-year-old black Labrador serving with the Lufkin Police Department, jumped from a ramp to chase a bird and fell, the Bureau of Alcohol, Tobacco, Firearms and Explosives said.
