The Jharkhand high court on Friday refused to extend the provisional bail of fodder scam convict and former Bihar Chief Minister Lalu Prasad and asked him to surrender by August 30 before the CBI court.

Hearing the prayer for extension of provisional bail for three months on grounds that the RJD leader needed to undergo treatment, Justice Apresh Kumar Singh asked Prasad to surrender by August 30 before the CBI court and directed the state government to provide medical care whenever needed.
