A bomb was targeted towards State Minister for Irrigation Amar Singh Pun in Rolpa district on Thursday.

Pun was on his way to take part at an assembly in Jaulipokhari when an unidentified group hurled the bomb at Bhakribang in Surbarnawati Rural Municipality-1. The bomb did not cause any physical damage, police said.

Following the attack, police tightened security around State Minister Pun and safely took him towards the assembly.

Rolpa police chief DSP Gyanendra Phuyal said they have heightened security following the incident.

Pun is contesting federal election from Rolpa from Nepali Congress.

There have been growing numbers of attack on election candidates in Rolpa district. Police suspected the Netra Bikram Chand-led Communist Party of Nepal might be behind the attack.

A week ago, former Finance Minister and CPN (Maoist Center) leader Barsha Man Pun was attacked in the district.
