Muammar Gaddafi's son Saif al-Islam has appeared with his supporters on the streets of Tripoli.
It had been reported that he was in the custody of opposition fighters.
A short time ago the National Transitional Council said that Saif either escaped, or because of the inexperienced nature of some of the rebels, was mistakenly set free.
"We are here. This is our country. These are our people and we live here and we die here. And we are going to win because the people are with us, that's why we are going to win. Look at them, look at them, in the streets - everywhere," Saif told the crowds.
