India's Olympic delegation walks in the opening ceremony, accompanied by an unknown gatecrasher wearing a red top and blue trousers
India's Olympic contingent is trying to identify a mystery woman who joined team members as they marched in the opening ceremony on Friday.
The woman, wearing blue trousers and a red top, walked next to India's flag-bearer, wrestler Sushil Kumar.
She stood out in contrast to athletes in yellow saris or blue blazers, reports the BBC.
India, already unhappy with its truncated TV coverage during the opening ceremony, is seeking an apology from the London organising committee.
"This was bizarre. We will ask for an apology," India's chef de mission, PKM Raja, told the Times of India.
"The Indian contingent was shown for just 10 seconds and to think this lady hogged all the limelight."
India is fielding 81 athletes at the London Games, with medal hopes in archery, boxing, badminton, shooting, tennis and wrestling.
