The Metropolitan Police is assessing new information it has recently received about the deaths of Princess Diana and Dodi Al Fayed in 1997.
In a statement, police said: "The Metropolitan Police Service is scoping information that has recently been received in relation to the deaths and assessing its relevance and credibility.
"The assessment will be carried out by officers from the specialist crime and operations command.
"This is not a re-investigation and does not come under Operation Paget."
Police said the deaths of Diana and Mr Al Fayed were "thoroughly investigated" and examined by an inquest led by Lord Justice Scott Baker at the Royal Court of Justice in 2007-2008.
On April 7 2008 the jury concluded its verdict as "unlawful killing, grossly negligent driving of the following vehicles and of the Mercedes", the Met said.
Police said they are not prepared to discuss the matter further.
Diana, Mr Al Fayed and chauffeur Henri Paul died after their Mercedes crashed in the tunnel, which left the Ritz Hotel on the morning of August 31 1997.
