"These are perhaps the only two words he knew in English. Nothing in Hindi. I also don't know Mandarin. But he appeared really distraught and was profusely perspiring, suggesting that he was in trouble. He also signalled that he was very hungry," added the SI.

Kuntal said that he gestured the man to come along in his car, whom he tried to explain that he was from the police to help him and somehow managed to convince him.

"Soon I called up a personal acquaintance of mine who works in a private agency as a translator, thinking he could help us. Most luckily, he knew Mandarin and then I put on the call on speaker and got the two talking and my acquaintance interpreting everything to me," said Kuntal.
