A local newspaper received an anonymous call about "some big news" in America 25 minutes before President John F Kennedy was assassinated, documents have shown.
The revelation was made in papers relating to the killing, which happened on November 22 1963.
A memo to the director of the FBI said the anonymous phone call was made to the senior reporter at the Cambridge News at 6.05pm on the day Kennedy was shot in Dallas, Texas.
The document, from deputy director James Angleton, said:
President Kennedy was shot as he rode in a presidential motorcade in Dealey Plaza at 12.30pm Central Standard Time, which is six hours behind Greenwich Mean Time.
The memo added that similar anonymous phone calls "of a strangely coincidental nature" had been received by people in the UK over the past year "particularly
in connection with the case of Dr Ward" - potentially a reference to Dr Stephen Ward, one of the central figures in the Profumo affair.
A copy of the memo, dated November 26 1963, was released by the National Archives in July this year, but had gone unreported until the latest batch of documents pertaining to the Kennedy assassination were released on Thursday evening.
