The Office of the Director of Public Prosecutions (ODPP) has directed the Independent Policing Oversight Authority (IPOA) to submit the file and report on the probe into the alleged shooting of Rex Masai within 21 days.
The Director of Public Prosecution Renson Ingonga has ordered IPOA to carry out thorough and comprehensive investigations into the matter.
"Pursuant to the provisions of Article 157(4) of the Constitution, the Director of Public Prosecutions has directed the Independent Policing Oversight Authority (IPOA) to carry out thorough and comprehensive investigations into the matter," the statement reads.
Thereafter, the resultant inquiry file together with the report should be forwarded to the ODPP not later than 21 days from the date hereof," the statement adds.
The ODPP reiterated the commitment to uphold the rule of law.
This comes hours after IPOA launched investigations into the shooting of Masai on Thursday by a person alleged to be a police officer.
He was allegedly killed during Thursday's anti-Finance Bill protests in Nairobi.
IPOA in a statement on Friday said an investigations team has since established contact with the family of Masai.
"The Authority has documented the death of Masai allegedly as a result of police shooting and several serious injuries suffered by other demonstrators including police officers," IPOA chairperson Anne Makori said.
The shooting took place at about 7 pm along Moi Avenue.
An aerial video captured the moment the victim was shot.
A group of protesters had been pushed by police from parts of Kenyatta Avenue, City Hall Way and other places they had gathered to air their opposition to the Bill when they gathered outside Moi Avenue.
They started to dance to music that came from a club at the site.
Witnesses claimed it was then that a cop in a cap and plain clothes emerged and started to shoot at the group while dispersing them.
Rex was hit in the leg and fell on the road crying for help.
Other protesters stopped for help and rushed him to Bliss Hospital Moi Avenue where he was pronounced dead while being attended to.
Officials at the clinic said a patient was brought into the facility by members of the public while unconscious with an injury on the thigh of his left leg but succumbed to the same while undergoing treatment.
