KATHMANDU: A man has been arrested on charge of killing his colleague cool-bloodedly in the Capital.

With deep cut wounds on the neck region and his private parts mutilated, the body of Ashok Khadka, who was in his early 20s, was found inside a vehicle, drenched in a pool of blood, at the Sagar Automobile Workshop in Mhaipi on July 17 morning.

Police identified the suspect as 32-year-old Umesh Bikram Bista aka Bigyan, a permanent resident of Makawanpur. Both of them worked at the workshop as mechanics.

A team of security personnel deployed from the Metropolitan Police Crime Division arrested him yesterday evening, nine days after the murder.

It has been revealed that Khadka and Bista had boozed together at the workshop in the evening of July 16 and a fight broke out between them apparently over Rs 100 which led to Khadka's murder, according to Metropolitan Police Crime Division.

Police investigation showed that Khadka had called up one of their colleagues at around 11:37 pm, to inform about the dispute.

Later Bishta further attacked Khadka and chased him to a vehicle, in which the latter went to hide, and impaled his body with a digging bar, according to preliminary investigation.

As Khadka lost his consciousness, Bishta pulled him outside the vehicle and pierced his body with the digging bar for five to six more times in a fit of anger. He then picked up a pair of scissors from the vehicle and cut the victim's penis and testicles, police said.

Covering the body with a blanket, the alleged murderer fled the scene, police said.

He walked to the New Bus Park area, Gongabu, and spent night there. In the wee hours of morning at around 4:30 am, he got on a microbus to Kalanki, and then went to Thankot to take refuge at the Makalu Workshop.

Police said the suspect has past criminal record.

Last year, he was jailed for two and half months for vandalism at a Gairigaun-based workshop where he worked, according to police.

Bishta has been sent to the Metropolitan Police Circle, Lainchaur, for legal action.
