It reads like the beginning of a Lee Child novel but passengers who spotted a woman clutching a rucksack and fervently praying have been commended for taking prompt action.
Fearing a terrorist suicide attack they raised the alarm on a morning London-bound First Capital Connect service.
The woman was met at King’s Cross and later released.
It was a false alarm, however police again warned the public and train crew to be vigilant and alert police if they see anything suspicious.
Stop the train/world I want to get off.
