Greg Kelly examined at Japanese hospital after securing bail

Nissan director Greg Kelly was being examined in a hospital on Wednesday, a source stated, one day after he was released on bail from a Tokyo jail where his ousted boss Carlos Ghosn is still being detained.

Kelly, who was released late on Christmas Day after over a month in detention, has been charged with conspiring to under-report Ghosn’s earning. He posted bail of 70 million yen ($640,000).

Their November 19 arrests jolted the international auto industry and has strained Nissan’s alliance with Renault SA. Nissan’s board fired Ghosn as chairman in previous month and Kelly as representative director, although both men technically still remain board members who can only be ousted by shareholders.

Kelly suffers from spinal stenosis, causing numbness, tingling and shooting pain in his extremities, according to his wife, Dee Kelly. The condition compresses or pinches the spinal cord.

Those symptoms worsened in these five weeks in the Tokyo Detention Center, his wife stated, citing Kelly’s lawyer.

Kelly was scheduled to have surgery on December 7 in Nashville, Tennessee, but flew to Japan in November after being told that he was needed in person at a board meeting, Dee Kelly stated. Kelly was arrested soon after his arrival.

Under the conditions of his bail, Kelly is prohibited from traveling overseas and his residence must be restricted to a designated place, the Tokyo District Court stated. Lawyers state that travel exceptions can be made on a case-by-case basis.
