New Delhi, India (AHN)-In an effort to keep monkeys out of the New Delhi 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 reports that 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.

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

According to the report, 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 more such problems.
