Reports indicate that the youths were subjected to mistreatment during the confrontation, leading to widespread criticism and calls for accountability.
Residents and youth groups have demanded justice, saying such actions damage trust between the police and the community.
Senator Cherargei, while addressing the matter, said it was troubling that no arrests had been made despite the presence of surveillance footage.
He argued that CCTV cameras are installed to provide evidence in such cases and help authorities establish what happened.
According to him, failure to take action when such evidence is reportedly available raises serious questions about accountability within law enforcement agencies.
The senator directly challenged IPOA, the body responsible for investigating police misconduct, to explain the steps it has taken regarding the incident.
He asked whether the authority had launched a full investigation and whether disciplinary measures were being considered against the officers involved.
Cherargei stressed that IPOA was established to ensure police officers follow the law and respect human rights while carrying out their duties.
The Nandi Hills incident has drawn strong reactions from residents who say young people should feel safe in public spaces without fear of harassment or violence.
Community leaders have also called for a transparent investigation to establish the truth and ensure justice is served if wrongdoing is confirmed.
Human rights activists have echoed these concerns, stating that cases involving alleged police brutality must be handled swiftly and openly.
They argue that delays in investigations or lack of visible action can weaken public confidence in institutions tasked with protecting citizens.
Activists have also urged witnesses to cooperate with investigators and provide any available evidence that could support the case.
IPOA plays a key role in monitoring police conduct and investigating complaints from members of the public.
The authority has the mandate to recommend disciplinary or legal action against officers found guilty of misconduct.
However, critics often accuse the oversight body of taking too long to conclude investigations, especially in high-profile cases involving alleged abuse of power.
Security experts note that accountability in policing is important for maintaining public trust and improving cooperation between law enforcement officers and communities.
They say that addressing complaints quickly and fairly helps strengthen confidence in security institutions and prevents repeated cases of alleged misconduct.
