From The BBC:

Russian ‘ninja’ arrested in Italy

Italian police have arrested a Russian “ninja” who had been spreading fear across farmlands in the north of the country.
The man, camouflaged in an all black suit, had robbed several farmers and their families at knife point, police say.

Police had been searching for him for several weeks.

Ninjas were trained for stealth. They first appeared in 14th Century Japan and were famed as assassins and spies.

Outwitted

For several weeks the police had been scouring the countryside looking for shadows.

The “ninja” was known to have struck several times - his head wrapped in a black bandana, a powerful bow in one hand and a knife strapped to his leg.

He targeted isolated farms late at night forcing farmers to hand over cash and valuables at arrow point.
