Border controls tightened as Japan investigates how ex-Nissan boss skipped bail

Reports have emerged about how the fugitive former Nissan boss Carlos Ghosn managed to jump bail in Japan, as the country’s justice minister said border controls would be bolstered after the audacious escape.

The 65-year-old executive skipped bail nearly a week ago, fleeing Japan where he had been awaiting trial on multiple counts of financial misconduct, which he denies.
