Pakistani singer Rahat Fateh Ali Khan was arrested by India's Directorate of Revenue Intelligence (DRI) on Monday, a day after he was detained at the international airport here for carrying undisclosed foreign currency worth more than $100,000, an official said.

"He has been arrested and will be produced in Patiala House court later today (Monday)," a DRI official said. Rahat had been taken to the DRI office at the CGO Complex Sunday after he was detained at New Delhi's Indira Gandhi International Airport Sunday.
