London (CNN Business) A Turkish company that charters private jets says a rogue employee helped fugitive auto executive Carlos Ghosn escape from Japan to Lebanon.

MNG Jet said in a statement Friday that two of its jets were used "illegally" to transport Ghosn without the knowledge of company management. The company said it has filed a criminal complaint.

MNG said it had leased two separate planes to different clients that did not appear to be connected. One was chartered from Dubai to Osaka and then Osaka to Istanbul, while the other was booked from Istanbul to Beirut.

Turkish police launched an investigation into Ghosn's escape on Thursday, detaining seven people on suspicion of involvement in the plot.

One employee under investigation by Turkish authorities had admitted to falsifying records, according to MNG.
