London stirred up
a man with a blue shirt with wires protruding. In a memo to hospital staff, officers asked employees to look for a black or Asian male, 6 feet 2 inches tall, wearing a blue top with a hole in the back and wires protruding.
A witness recalls:
"He said that a man was carrying a rucksack and the rucksack suddenly exploded. It was a minor explosion but enough to blow open the rucksack," McCracken said.
More as it becomes available.
