New Delhi, Apr 13 (IBNS): US Customs and Border Protection (CBP) authorities on Friday apologized for the detention of Bollywood superstar Shah Rukh Khan at a New York airport on Thursday.

The US CBP has reportedly sent a letter to the Indian consulate in the US and apologised for detaining Shah Ruukh Khan.

However, India reacted strongly against the entire episode as External Affairs Minister SM Krishna directed Indian ambassador to US Nirupama Rao to take up the matter with concerned authorities.

Strongly criticizing the incident, SM Krishna said it has become a 'habit these days to first detain' people and then 'apologise'.

"This can't continue," Krishna said.

Congress MP Rajiv Shukla told reporters: "This is not fair. They should maintain records and a person who has once gone through the entire procedure should not be forced to go though it again. For well-known figures data bank should be maintained."

"The Foreign Minister has already condemned the matter," Shukla said.

Jammu and Kashmir Chief Minister Omar Abdullah tweeted: "Honestly what's the big deal?? This airport detention thing happens all the time & to all sorts of people. Get over it."

Shah Rukh said he was detained for two hours at a New York airport on Thursday.

He arrived at New York's White Plain airport in a private plane on Thursday to address Yale University students after being named a Clubb Fellow.

According to officials, Khan was stopped for two hours for his immigration clearance.

The university officials had to intervene and get Khan out of the airport with the help of the Department of Homeland Security and the Immigration and Customs Department in Washington.

While addressing the students at the university, Khan confirmed the news and said he was 'detained' at the airport 'as it always happens'.

In 2009, Khan was detained and grilled for two hours at Newark Airport as he was heading to Chicago to participate in an Independence Day celebration.
