Why did leopards kill people in Mumbai?

Officials have caught three leopards in Mumbai. The big cats have killed 12 people during the last month, causing panic among local residents. It’s a classic case of survival of the fittest and the fight for space between man and beast. All the more difficult in a city like Mumbai, whose burgeoning population is increasingly pushing deep into the forest. The forest, which is Mumbai’s green lung, is also a wildlife sanctuary and the leopards’ natural habitat. But, in the last few months, the big cats have increasingly emerged from the forest and into the urban jungle, killing 22 people including children. Residents are up in arms about what they call "official apathy", but forest officials say it’s up to residents to take great care in the face of an unexpected threat.
