Police criminal investigations department officer Christopher Naphiyo was arrested by fellow law enforcers after he was overheard boasting at a drinking joint in Lilongwe that he knows assailants of former Anti Corruption Bureau (ACB) corporate affairs director Issa Njauju.
Sources in the police say some people, whom he was drinking with at Falls in the capital city reported him to police after he boasted he knew the killers of Njauju.
His is yet to be charged after he was arrested on Friday.
Police headquarters spokesperson Nicholas Gondwa refused to give detailed account on the arrest of Naphiyo who was based at police headquarters.
His pals describe Naphiyo as a reticent cop who has very few friends whom he interacts with.
Naphiyo is the second person to be arrested in connection with the death of Njauju after the arrest of another man who has since been charged with murder after he was found with a mobile phone belonging to the graft busting body’s third in command.
ACB director Lucas Kondowe could also not give information on the arrest of Naphiyo only saying his organisation is closely working with the police to ring to book the murderers of Njauju.
Civil society organisations are putting pressure on government to do more in order to arrest the killers of Njauju who was brutally murdered in July and his half buried body was found near presidential villas in Lilongwe.
