"Four out of 10 people have false memories of the 7/7 London bombings, according to researchers who questioned students about what they remembered seeing on news reports of the events.

Some people claimed to have seen non-existent CCTV footage of the bus exploding in Tavistock Square in July 2005, while others gave detailed descriptions of footage which did not exist...

Some of the students embellished their accounts with details they could not have witnessed. One wrote: "The bus has stopped at a traffic light. There was a bright light and a loud bang and the top of the bus flew off."

The study backs up previous research by [Dr James Ost, a psychologist at the University of Portsmouth] in which people claimed to have seen non-existent footage of the crash in Paris that killed Princess Diana."
