Bihar BJP president Gopal Narayan Singh, who had accompanied Advani in the helicopter, told PTI that the DPM had left for Patna by road.

Singh said the 'Rajhans' helicopter carrying Advani and others from Bhagalpur to Patna was caught in a hailstorm a few minutes before it reached Patna airport forcing the pilot to make an emergency landing at Fatuha.

Advani will fly to New Delhi in the evening in a special plan from Patna airport.
