There are an estimated 5,000-7,000 wild monkeys roaming the streets of Delhi and all earlier attempts to control them have failed.
Witnesses say a monkey on the roof of the building pushed at least two pots over the edge.
One of them hit Mr Jha on the head, killing him instantly. Press reports on the incident say there have been many complaints in the area about the increasingly bold and dangerous behaviour of local monkeys. A doctor was quoted as saying he treated about 15 monkey bites every month. The wild monkeys are an acute problem for the city authorities. Aside from biting people, they destroy property, get into houses and offices and wreak havoc, and steal food from picnickers and street vendors.
