NEW DELHI: India charged a well-known Pakistani singer with currency violations on Saturday after he and his entourage were allegedly caught with $124,000 in undeclared cash at New Delhi's airport, reports said.

Rahat Fateh Ali Khan and his group were boarding a plane to Lahore via Dubai last Sunday when authorities alleged they found the money in their bags.

Thirty-seven-year-old Khan is accused of carrying undeclared foreign currency in violation of India's Foreign Exchange Management Act and customs rules, the Press Trust of India and other media reported.

Khan's manager Maroof, who goes by one name, faces similar charges, the reports said.

The singer was stopped at the airport and his passport confiscated after performing a string of concerts in India.

According to Indian customs rules, visitors are allowed to carry only $5,000 in cash in and out of the country.

A spokesman for the Pakistan High Commission (embassy) in New Delhi said he was not immediately aware of the charges.

But the Pakistani foreign ministry said in Islamabad earlier in the week it was “closely monitoring the situation”.

Authorities could impose “heavy penalties” on Rahat and his manager, the Press Trust of India said, quoting unidentified official sources.

It was not immediately known what penalties the pair could face.

Khan's agent Yusuf Salahuddin said the singer was perhaps unaware of India's stringent foreign currency laws.

“He was in India for 10 days and did about seven concerts all across the country and this must have been some of the money which possibly was given to him at the airport,” he told Times Now TV station earlier this week.
