Tokyo prosecutors say they have obtained an arrest warrant for Carole Ghosn, the wife of former Nissan Motor chairman Carlos Ghosn.
She is suspected of giving false testimony last April at her husband's trial for alleged aggravated breach of trust.
Prosecutors say that she denied knowing an Indian executive of a Nissan dealership in Oman who was involved in the case, even though she had exchanged text messages with the official many times.
Prosecutors believe Ghosn channeled Nissan funds through the executive's private account to a firm in whose management his wife was involved.
She is believed to be in Lebanon with Ghosn, who secretly left Japan while out on bail and entered Lebanon on December 30.
The prosecutors are expected to ask Interpol to put her on an international wanted list.
