By Naomi Tajitsu TOKYO, April 5 (Reuters) - Ousted Nissan boss Carlos Ghosn is back in the Tokyo detention centre where he previously spent 108 days, after being released just last month on a $9 million bail. Prosecutors arrested the once-feted executive on fresh charges of financial misconduct on Thursday. Ghosn has said he is innocent of all charges and the victim of a boardroom coup. His lawyers have accused Japanese prosecutors of trying to muzzle him. His former employers, Japan's Nissan and France's Renault, initially appeared to be at odds over his case when he was first arrested in November, but now seem to have closed ranks against him. WHAT ARE THE NEW ALLEGATIONS, HOW ARE THEY DIFFERENT? Ghosn was arrested again on suspicion of funnelling $5 million from payments made by a Nissan subsidiary to a third party for personal gain. An internal Nissan investigation has identified the party as a Nissan distributor in Oman.
