Jack the Ripper was a twisted Metropolitan Police officer, a historian claims. Author Rod Beattie spent 20 years trawling national archives.
He believes Britain’s most notorious serial killer – who terrorised East London in 1888, slaughtering five women – was an aggrieved police constable.
Mr Beattie says the culprit was Bowden Endacott, a reserve Met Police officer who would have been patrolling the streets of Whitechapel.
