TOKYO (Reuters) - A surveillance camera captured former Nissan Motor Co chairman Carlos Ghosn leaving his Tokyo residence alone shortly before his surprise escape from Japan, public broadcaster NHK said on Friday, citing investigative sources.

The security footage was taken by a camera installed at his house in central Tokyo around noon on Sunday, and the camera did not show him returning home, NHK said.

Ghosn has become an international fugitive after he revealed on Tuesday he had fled to Lebanon to escape what he called a “rigged” justice system in Japan, where he faces charges relating to alleged financial crimes.

NHK said the police suspected Ghosn may have left his home to meet up with someone before heading to an airport. Under the terms of his bail, Ghosn was required to have security cameras installed at the entrance of his house.

Lebanon received an Interpol arrest warrant for Ghosn on Thursday while Turkey has launched an investigation into his escape from Japan, via Istanbul.

Some Lebanese media have floated a Houdini-like account of Ghosn being packed in a wooden container for musical instruments after a private concert in his home, but his wife has called the account “fiction”.
