Newsflash: man detained on Heathrow runway

Just one day before the launch of Heathrow’s new Terminal 5, there has been a security breach at the airport. A man scaled a perimeter fence with a rucksack and ran into the path of an Emirates flight before being surrounded by police and police dogs.   He is thought to have been acting alone, but his motives and the contents of the rucksack have yet to be revealed. More from the BBC.
