India's anti-narcotics police Thursday raided Bollywood superstar Shah Rukh Khan’s house in the city of Mumbai, 18 days after they arrested his son Aryan in a cruise drugs case.

Sources told UNB that a team from the Narcotics Control Bureau (NCB) raided Shah Rukh's multi-storey house Mannat around noon in connection with the case and also got some paperwork done.

However, quoting unnamed NCB officials, some TV channels reported that the anti-narcotics sleuths visited Mannat only for "some paperwork relevant to the case".

The raid comes hours after Shah Rukh visited his son at Mumbai's high-security Arthur Road jail in the morning. Aryan has been in judicial custody since October 8.

Aryan was arrested by the NCB on October 3 after hours of grilling in connection with a rave party it busted on board a cruise ship near Mumbai a day before.

Acting on a tip-off, some 30 NCB sleuths, disguised as passengers, boarded luxury cruise liner 'Empress' on October 2 evening, which departed the Mumbai port for the neighbouring state of Goa.

The cruise ship was carrying mostly celebrities from Bollywood and the fashion industry. As soon as the rave party began, the NCB sleuths swing into action and caught red-handed those consuming drugs.

Aryan, his close friend Arbaaz, and eight others were soon detained. While two of the detainees had been freed after questioning, Aryan and seven others were arrested.

Aryan's father Shah Rukh is considered the most talented Bollywood star. Popularly called the "King Khan", he has acted in over 80 films in a career spanning over 25 years.

Shah Rukh, in fact, rose to prominence after starring in 1995 romantic film 'Dilwale Dulhania Le Jayenge', the longest-running blockbuster in the history of Indian cinema. The film was shot in India and Europe.

Some of his other blockbusters include 'Dil To Pagal Hai' (1997) and 'Kuch Kuch Hota Hai' (1998). Shah Rukh was also widely praised for his superb performance in 2002 film 'Devdas', where he played an alcoholic. 

The 55-year-old has also anchored many TV shows, and owns production company Red Chillies Entertainment and Indian Premier League cricket team Kolkata Knight Riders.

Shah Rukh has a net worth of USD 700 million. The superstar is married to interior designer Gauri Chibber, a Punjabi Hindu. Apart from Suhana, they have two sons.
