In an effort to keep monkeys out of New Delhi, and specifically out of the Indian capital’s subways, authorities have called in one of the few animals known to scare the creatures — a fierce-looking primate called the langur, the Hindustan Times newspaper reported.

The decision to hire a langurwallah — a man who trains and controls the langurs — came after a monkey got into a metro car in June, the newspaper reported.

The langur handler is being paid a retainer of India rupees 6,900 (US$160) a month, and "he will be called whenever there is a monkey problem," Anuj Dayal, the spokesman for the Delhi Metro Rail Corp., was quoted as saying.

On June 9, a monkey reportedly crawled through some pipes and ended up aboard a train, scowling at passengers and jumping around a car.

Passengers had to be moved to another car while staff chased the dexterous creature, causing delays.

The langur handler was being employed to prevent such problems from happening again.

"There are too many monkeys," Dayal was quoted as saying.
