TOKYO (AFP) - Local authorities hunting for a gang of monkeys who attacked and wounded nearly 50 people in western Japan have caught and killed one of the marauding primates, an official said on Wednesday (July 27).

The male monkey was seized while roaming the grounds of a high school in Yamaguchi city - but it may not be the end of the furry, twisting tale, with other monkeys feared to be at large.

City officials have been trying for weeks to track down the vicious gang which have made national headlines by assaulting residents with mostly mild scratches and bites.

On Tuesday evening, specially commissioned hunters shot the monkey with a tranquiliser gun and eventually caught it near a lake on the school premises, an official at the local agricultural department told AFP.

After identifying it as the same animal responsible for one of the attacks, the monkey was put down, he said. It had an estimated age of four and was around half a metre tall.

Patrols have been under way in Yamaguchi since the attacks on adults and children began around three weeks ago.

But with 49 people injured as at Tuesday midday and fresh attack reports coming in, the search is still on.

"Eyewitnesses describe monkeys of different sizes, and even after the capture, we've been getting reports of new attacks," said the city official, who declined to be named.

Japanese macaques are seen commonly across large parts of the country, and are a pest in some areas, eating crops and even entering homes.

But the spate of attacks in Yamaguchi is unusual, with some residents telling local media that they are now carrying umbrellas and tree-cutting scissors to defend themselves.
