Turkish authorities on Thursday questioned seven people, including four pilots, about the role they may have played in helping Carlos Ghosn make his escape from Tokyo to Beirut, offering new clues to his mysterious flight.

Elsewhere, prosecutors raided Mr. Ghosn’s home in Tokyo, a Lebanese government minister said the public prosecutor had received a “red notice” — an alert that’s akin to a wanted poster — from Interpol, and a French official said authorities there would not extradite Mr. Ghosn if he were to travel to the country.

Four days after Mr. Ghosn triumphantly announced his arrival in Beirut, law enforcement officials and authorities were left grappling with the legal implications of the former automotive executive’s stunning escape, whose details remain shrouded in mystery.

Mr. Ghosn, the former chief executive of Nissan and Renault, left Japan on Sunday to avoid trial on financial misconduct charges there, though his movements were supposed to be strictly limited while he was free on bail. He turned up in Lebanon, saying he had escaped the “rigged Japanese justice system.”
