Yamaha warns not to go inside musical instrument cases after ex-Nissan chief's escape from Japan

The Japanese music company appears to be poking fun at the fugitive.

"Musical instrument and audio equipment cases are designed to hold musical instruments and audio equipment," the company added in a follow-up tweet. "Please use them correctly."

Ghosn's saga has sparked international intrigue after he jumped bail and mysteriously fled Japan while awaiting trial for charges of financial misconduct.

The former chairman of Nissan had been under 24-hour surveillance at his Tokyo home awaiting trial, but somehow managed to slip out of the country undetected on a private jet, arriving in his homeland of Lebanon. Ghosn's charges carry a maximum penalty of 15 years in prison, according to The Associated Press.

The Wall Street Journal reported he hid in a box used for audio equipment to sneak out of Japan. Other outlets have reported he hid in a box used for a double bass.

Ghosn has maintained his innocence, saying he "escaped injustice and political persecution."

Nissan called its former chairman's escape "extremely regrettable" in a statement, and Japanese authorities have said they will take all measures to pursue criminal proceedings.

He is currently in Lebanon, living under a travel ban. Lebanon has no extradition treaty with Japan.
