Carlos Ghosn's escape: What we know

The Renault-Nissan alliance is looking to reboot after the Carlos Ghosn episode AFP/Behrouz MEHRI

Here's what we know about the former Renault-Nissan boss's flight:

HID IN AN INSTRUMENT CASE

The exact circumstances of his departure from Japan, where he was under house arrest pending trial, are still shrouded in mystery.

On Thursday, Kyodo News quoted an associate of Ghosn, Imad Ajami, as claiming the tycoon was helped by two private security operatives who pretended to be part of a music band for a Christmas party.

But speaking to AFP on Friday, Ajami said this scenario was "speculation".

"I don't know how he left" Japan, Ajami said in a phone interview, adding that he had had no direct contact with Ghosn since he left Japan.

A surveillance camera at his Tokyo residence showed him leaving alone around noon on December 29 and not returning after, according to public broadcaster NHK.

Police think there is a possibility he joined someone to head for the airport as no suspicious person was seen around the time that Ghosn left, NHK said.

Ghosn is believed to have taken a private jet from Kansai Airport in western Japan on Dec 29, to Istanbul.

It is thought he then flew from there to Beirut.

TURKISH INVESTIGATION

Turkey's interior ministry has opened an investigation into Ghosn's apparent transfer between private jets at an Istanbul airport on Monday.

Officials questioned seven people, including four pilots, as part of the probe, news agency DHA reported Thursday.

The investigation is focused on two flights.

The first, a Bombardier labelled TC-TSR, flew from Osaka in Japan, landed in Istanbul at 5.15am and parked in a hangar.

The second was a private jet to Beirut, a Bombardier Challenger 300 TC-RZA, which left 45 minutes later, according to DHA.

Ghosn said in a statement on Thursday that he acted alone without his family's help.

FOUR PASSPORTS

There is no emigration data showing Ghosn's departure from Japan but he entered Lebanon on a French passport, according to airport documents seen by AFP.

Lebanon said the former car mogul - who holds Lebanese, French and Brazilian nationalities - had entered the country "legally" at dawn on Monday.

A source close to the matter told AFP, however, that the Tokyo court had nonetheless allowed Ghosn to keep a second French passport so long as it was kept "in a locked case" with the key held by his lawyers.

"RED NOTICE"

Interpol, the international police cooperation body, has issued a "red notice" for Ghosn's arrest in the wake of him fleeing Japan.

However, a Lebanese judicial source told AFP that Beirut and Tokyo do not have an extradition agreement under which Ghosn could be sent back to Japan.

Ghosn stands accused in Japan of deferring part of his salary until after his retirement and concealing this from shareholders, as well as syphoning off millions in Nissan cash for his own purposes.

His home in France was searched in June as part of a probe into his sumptuous marriage celebrations at the Palace of Versailles in 2016.

And three lawyers in Lebanon submitted a report to the public prosecutor on Thursday demanding that the businessman be prosecuted for a trip he made to Israel in 2008.

Details of just how he escaped could be clarified on Monday when the former auto executive is to speak to the press in Beirut.
