Pakistani man speaking fluent English at Karachi airport arrested by security persons after they mistook him for an Indian

A strange thing happened at a Pakistani airport today when security persons arrested a Pakistani national as he was speaking fluent English.
People speaking fluent English in Pakistan are very few. So it is quite obvious that security personnel had a doubt when they saw Ahmed Shah speaking fluent English.

The mistake Ahmed did was that he was grammatically correct, something rarely seen in a Pakistani. As soon as he uttered a full sentence in English without any mistake, he was arrested by the airport police. He was only released after he showed his passport and other documents. Rameez Raja is too scared from the incident and has been learning Punjabi and Urdu to convince people that he is a Pakistani.

Most of the people in Pakistan have a doubt that Rameez does have some connection with India.
