Turkey makes arrests as Carlos Ghosn's Tokyo home raided
Ghosn, who faced multiple charges of financial misconduct that he denies, won bail in April but with strict conditions - including a ban on overseas travel.
But the disgraced executive, who has French, Brazilian and Lebanese nationalities, managed to slip out of Japan on Sunday despite having handed over his three passports to his lawyers.
A court in Tokyo had allowed Ghosn to keep a second French passport as he needed one to travel inside Japan, a source close to the matter told AFP on Thursday.
"He had to keep this passport" to prove his short-stay status, the source said, adding: "There was permission from the court."
Ghosn was allowed this French passport so long as it was kept in a locked case with the code held by his lawyers, the source said.
There is no emigration data showing Ghosn's departure from Japan but he entered Lebanon on a French passport, public broadcaster NHK said.
Colourful rumours abound regarding the exact circumstances of Ghosn's daring escape.
One claim in the Lebanese media was that the mogul was sprung from his Tokyo residence in a musical instrument case - a story a source in his entourage denied.
He is thought to have taken a private jet from Kansai Airport in western Japan on 29 December, heading for Istanbul. It is believed Ghosn headed from there to Beirut.
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.
