The London Metropolitan Police said that there is “no credible evidence” to support a claim that the British military was involved in the deaths of Princess Diana, her boyfriend and their driver.

The allegation first surfaced in August, 16 years after the Princess died in a Paris car crash. Officers were tasked with looking into whether there was any truth to it.

“Every reasonable line of enquiry was objectively pursued in order to fully evaluate any potential evidence,” police said in a statement released overnight Monday.

“The final conclusion is that whilst there is a possibility the alleged comments in relation to the Special Air Service’s (SAS) involvement in the deaths may have been made, there is no credible evidence to support a theory that such claims had any basis in fact.”

Wildly popular in life and death, Diana died on August 31, 1997, after the car she was riding in slammed into a pillar in a Paris overpass. Her boyfriend, Dodi Fayed, and their driver, Henri Paul, also died.

Investigators concluded that Paul was drunk and speeding when the accident occurred.
