This story is being widely reported -- Here's the Flopping Aces version.
Seems a just-retired Gurkha was on a train that was being robbed by 40 bandits. When they attacked an 18-year-old girl intending to rape her, the Gurkha pulled his Khukuri (or Khukri -- there's 40 ways to spell it, too) and went to work. He killed three, wounded eight, and scared the crap out of 29 more armed men to the extent that they dropped their loot and fled in terror. Can't say that I blame them. I'm not afraid of khukuri's but I am afraid of Gurkhas.
