Four people have been arrested on Tuesday in connection with the assassination of Nepal's Armed Police Force Chief Krishna Mohan Shrestha.
A hunt is on to nab others involved in the killing, home ministry spokesman Gopendra Bahadur Pandey said in Kathmandu.
Police had arrested one suspect, Krishna Hari Sainju, who was found lying at the site of the incident with a bullet injury in his leg, while three others were arrested from the outskirts of the capital on the basis of the information given by Sainju, Pandey said.
According to a police spokesman, around 25 to 30 people are being questioned in this regard.
Sainju, who is under police guard at a hospital, has confessed to being a Maoist commander and said the rebels had been plotting Shrestha's assassination for a month, media reports said. But the police have not confirmed these reports.
Shrestha was killed on Sunday along with his wife and a bodyguard during his morning walk in Kathmandu, after heavily armed Maoist rebels opened fire on them.
