Offbeat diary of the Olympics: Day Two

The second day of the London 2012 Olympics started with an investigation into empty seats at venues and hopes for Team GB's Rebecca Adlington in the swimming heats.

Here's a look at what else is happening while all the sport is being played out.

The woman who unexpectedly appeared in India's Olympic contingent in the opening ceremony has been identified.

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.

"She didn't just walk in off the street," explained London 2012's Seb Coe. "She was a cast member who got slightly over-excited.

"She shouldn't have been there but she clearly started in that venue."

India's chef de mission, PKM Raja, had told the Times of India he wanted Olympic organisers Locog to apologise. Lord Coe added: "I will be speaking to the Indian delegation."

We've heard a lot about the importance of family support for athletes and Rebecca Adlington has plenty of that from her relatives.

She had to work hard to get into the 400m freestyle final and here's a picture of "Team Adlington" who were cheering her on.

Spectators from New Zealand and Australia have been enjoying festivities at the Olympic Park.

Natalie Whittaker made an Olympic fascinator, Peter Kelly has brought his friend "Skippy" and Stephanie Whittaker has been wearing New Zealand sunglasses.

Australia's Cate Campbell, who won gold in the in the women's swimming 4 x 100 metre freestyle relay final, said: "I think this is one of the first things that ran through my head when I touched the wall. I get to be on a stamp and I get to fly home business class.

"Terrible I know. It's just one of those exciting things that comes with being a gold medallist."

Former Formula 1 World Champion and Indy 500 winner Emerson Fittipaldi tweeted his delight at Brazil's medals for judo and swimming: "Congratulations to our three Brazilian medalists yesterday @ the London Olympic Games, historic 1st day for #Brazil -best ever-good job #BRASIL!"
