The incident occurred after the helicopter took off from Sonbarsa Raj, where he had gone to address an election rally, to fly to Madhepura to address another public meeting this afternoon, Saharsa SP Sunil Kumar Nayak said.
"The storm continued for almost an hour from 4.30 pm to 5.30 pm. It started after the chief minister had left the rally venue. The helicopter in which he was flying to Madhepura was trapped in the storm. The pilot somehow managed to make emergency landing at the place he flew from," Nayak said.
"The chief minister and members of his entourage left Saharsa via road to Madhepura where he had another engagement," Nayak said.
Kumar is currently campaigning in Madhepura, Darbhanga, Jhanjharpur, Madhubani, Samastipur (SC), Begusarai and Khagaria constituencies which are going to polls in the fourth phase of Lok Sabha elections in Bihar on April 30.
