Bolt unaware of 100m track incident

100m Olympic champion Usain Bolt has said he was unaware of a bottle that was thrown onto the track at the start of the final.

The 25-year-old, responding to questions about the incident from reporters, said: "No, I keep hearing that. I don't know who would have done that."

Fellow Jamaican sprinter Yohan Blake said: "I was so focused I didn't see anything. I was so focused on just running to the line."

Edith Bosch, Holland's world judo champion, claimed on Twitter that she had "beaten" the person who had thrown the bottle.

She said: "A drunken spectator threw a bottle onto the track! I HAVE BEATEN HIM .... unbelievable."

Nobody was injured during the incident and the event was not disrupted, police said.

The suspect is being held in police custody at an east London police station on suspicion of causing a public nuisance.
