Police on Tuesday arrested two persons on charge of attacking filmmaker 'Roj Rana' with Khukuri in Old Baneshwor, Kathmandu.

Rana, whose original name is Saroj Thapa, had sustained injuries in his upper limbs after the attack on Monday night.

The Metropolitan Police Crime Division identified the arrestees as Bibechan Prajapati aka Mote, 28, of Bhaktapur and Surya Lama aka Katunje, 18, of Dhading.

According to police, the mastermind of the attack Ratna Bahadur Lama is on the run. Lama had promised to pay Rs 3 million if the duo succeeded in inflicting serious physical harm to Rana.

"Rana and Lama were partners in various extortions. Their relationship soured over monetary issues and later Lama orchestrated the attack," said SP Sahakul Thapa, spokesperson of MPCD.

On August 15, Prajapati wielded a khukuri as Surya drove the motorbike following Rana from early in the morning. After failing to attack him in Bagbazar and Durbarmargh, they eventually assaulted him in Old Baneshwor.

Rana, a native of Puythan, has long been involved extortions among other illegal activities. He was close to notorious gangster Dinesh Adhikari, Chari, who was shot dead by police in August 2014. Police had been scrutinising Rana after a SUV seized from Chari in 2011 belonged to him.   

Rana has also been accused of running a prostitution racket.
