Yamaha Corporation reportedly has warned people not to try and squeeze inside musical instrument cases after news former Nissan Motor chief Carlos Ghosn fled Japan concealed inside one.

"We won't mention the reason, but there have been many tweets about climbing inside large musical instrument cases. A warning after any unfortunate accident would be too late, so we ask everyone not to try it," the maker of speakers and musical instruments said in a post on its twitter account, Reuters reported.
