KATHMANDU: Sadbhawana Party Chairman Rajendra Mahato, who was injured in police action in Nepal-India border point in Biratnagar on  December 26, was airlifted to New Delhi for further treatment on Friday as his condition did not improve, according to his party leaders.

Mahato had sustained injuries on various parts of his body during a violent clash with police at the Jogbani-Biratnagar border point, and was admitted to the BP Koirala Institute of Health Sciences in Dharan.

Sadbhawana Party Co-Chairman Laxman Lal Karna told THT Online over phone from Birgunj some minutes before Mahato's flight to New Delhi from Kathmandu that the party chairman would be taken to the Indian capital as his wounds did not get healed in these seven days.

His blood pressure and blood sugar also could not be controlled, which further worsened his condition, according to Karna.

Mahato boarded an Air India flight to New Delhi this afternoon, according to Upendra Mahato, who is a member of the Sadbhawana Party's Central Committee and leader Mahato's kin.

The Air India was first reluctant to fly the leader citing risk of brain haemorrhage owing to high blood pressure (184/107), Upendra Mahato wrote in a Facebook Post.

The flight captain, however, granted him permission to board the flight after a doctor from Norvic Hospital carried out a check-up on an ambulance at the airport, gave medicines and certified in writing that he was "fit to fly without supportive oxygen in sitting position.

Mahato's Sadbhawana Party is one of the key constituents of the United Democratic Madhesi Front, which has been protesting the recently promulgated Constitution.
