Moscow: Not satisfied with the US regret over detention of Shahrukh Khan at an airport for the second time, India on Saturday said "mechanical apologies" will not help and the US should have a serious look at its procedures to ensure there is no repetition.

"I am rather surprised that this should repeat in the United States... even last time an apology was given to us but again there is a repetition of the same. So this mechanical apologies are not going to improve matters," External Affairs Minister S M Krishna said.

"They (the US) will have to seriously look into the procedures which they have put in place. They should be helpful in our bilateral events," he said.

Shahrukh, on his way to address students at Yale University, was detained by immigration officials for nearly two hours after arriving in a private plane at White Plains Airport, about 53 kilometres from Manhattan. He was given immigration clearance after intervention by the Consulate General of India (CGI) and the US Customs and Border Protection authorities expressed "profound" apology in a letter to the Mission.

Krishna recalled that Shahrukh was detained earlier also in 2009 and the Indian Consulate General in New York had to intervene to get him out.

"We thought that was behind us. But again the same act has been repeated when he (Shahrukh) went there day before yesterday," Krishna said.
