A 来源 told the Daily Mirror newspaper: 'It was pretty terrifying for everyone concerned. All five boys, plus two members of the crew, were in their tour bus when the car rammed into the back of it.

'Thankfully, it withstood most of the impact but obviously, travelling at speed, the boys' couldn't avoid whiplash. After careering across the road, both vehicles came to a stop. Louis, Zayn and Niall were the worst affected.

'Paramedics advised management to scrap the 演出, gig in Plymouth but because the boys didn't want to let anyone down they agreed to go ahead.'

Despite soldiering on with the concert, the boy band were 'really shaken up' 由 the incident.

Another 来源 told The Sun newspaper: 'It was a close call. The lads and their two tour managers were pretty shaken up, but yesterday they were seen 由 an osteopath who gave them the all-clear.'

Niall took to twitter to thank all One Direction 粉丝 for their support and reassure them the group are 'absolutely fine'.

He wrote: 'Guys, thanks for all 你 messages. We were involved in a really minor accident - we are all absolutely fine!'
