Update 14:03: Police Constable Emmanuel Ambunya Oyombe accused of killing Carilton Maina will undergo a mental examination at Mathari Mental Hospital in Nairobi.
The directive was issued by High Court Judge Ngenye Macharia when the accused appeared before the court on Thursday, April 16.
Following the presentation of the medical report to the court on April 23, the officer will face murder charges.
The Directorate of Criminal Investigations (DCI) arrested a police officer in connection with the murder of Carilton David Maina in 2018.
According to a public statement by the investigative body, Constable Emmanuel Ambunya Oyombe was arrested on Wednesday, April 16 and will be arraigned in court on Thursday, April 16.
The police officer will be charged with the murder of the 23-year old student who died from gunshot wounds on a fateful night while in Laini Saba, Kibra.
"Following the completion of an inquest into the death of Carilton David Maina on 22nd December 2018 at Laini Saba in Kibera, Constable Emmanuel Ambunya Oyombe of KNH Police Post was today arrested & to be charged for the offence of Murder C/Sec 203 as read with sec 204 of the Penal Code," read the statement in part.
The high profile murder drew international condemnation and threatened to spark protests in Kibra with human rights organisations blaming the government for the extrajudicial killings in informal settlements.
Maina, who was at the time an electrical engineering student at the University of Leeds in England had returned to Kenya from West Yorkshire to be with his family for Christmas.
Reports hold that the officer who killed him followed him into an alley and shot him four times: on his ankle, stomach, chest and face even as Maina pleaded for his life.
The engineering student attempted to crawl to his mother's house which was just 50 metres away but never made it.
Close friends insisted that Maina was not a criminal as the police attested. He was lauded by those who knew him a remarkable young man with a bright future.
Amnesty International welcomed the arrest of the officer and asked for continued efforts to get justice for Maina.
"Amnesty Kenya welcomes the arrest of Constable Oyombe for the brutal murder of Carilton Maina...May justice be served," read the statement in part.
