Turkish authorities have detained seven people as part of an investigation into how former Nissan chairman Carlos Ghosn was able to flee to Lebanon via Istanbul, according to reports.
The state-run Anadolu Agency in Turkey said the seven people are suspected of aiding Mr Ghosn.
NTV television said the probe was launched by launched by Turkey's Interior Ministry.
The private DHA news agency reports that those detained are 4 pilots, a cargo company manager and two airport workers.
Mr Ghosn fled to Lebanon this week before his trial in Japan on financial misconduct charges. Turkish media reports said he flew to Lebanon on a private jet via Istanbul.
Lebanon has said that Mr Ghosn entered the country legally and there was no reason to take action against him.
Japan does not have an extradition treaty with Lebanon.
Mr Ghosn, who was charged with under-reporting his future compensation and a breach of trust, has repeatedly asserted his innocence.
He says Japanese authorities trumped up the charges to prevent a possible fuller merger between Nissan Motor Co. and alliance partner Renault SA. Before his arrest, Mr Ghosn was chairman of both Nissan and Renault.
His 1.5 billion yen ($14 million) bail that Mr Ghosn posted on two separate instances to get out of detention is being revoked.
