Track invader sprints across circuit at Chinese GP
A man runs across the track during second practice for the Chinese Grand Prix.
The man, who was later arrested, crossed the main start/finish straight in front of Force India's Nico Hulkenberg and climbed the fence and ran into the pits before reportedly trying to enter Ferrari's garage.
Formula 1 bosses will investigate how the tight security measures, which are imposed at all races, were breached.
