The murder of teacher Albert Ojwang while in police custody at the Central Police Station has triggered an extensive investigation, leading to the surrender and arrest of numerous individuals, including high-ranking police officers and civilians. On Monday, Deputy Officer Commanding Station Samuel Ngán’ga and Cell Sentry Peter Kimani surrendered to the Independent Policing Oversight Authority (IPOA), bringing the total number of police officers in custody to four. These two officers were on duty when Ojwang was brought in from Homabay by DCI detectives and are alleged to have received instructions to plan his torture. So far, at least 17 police officers involved in the saga have been identified and questioned.

The unfolding events have already prompted the stepping aside of Deputy Inspector General of Kenya Police Service Eliud Lagat, who had previously complained of false publication before Ojwang's arrest and subsequent death. In addition to the police officers, four civilians are also currently in custody over the incident. A 23-year-old technician was detained for 14 days by a Kahawa court on claims of tampering with CCTV footage at the Central Police Station, allegedly paid Sh3,000 to disable the surveillance system. A second suspect, believed to have been inside the cells during the fatal incident, was also arrested and detained. IPOA's Assistant Director of Forensics, Paul Njihia, stated that the tampering significantly hampered investigations into whether Ojwang was tortured and killed inside the police station cells, necessitating the seizure of their mobile phones for forensic analysis.

Central Police Station OCS Samson Talaam was arrested and remains in custody at Lang’ata Police Station. IPOA has filed a miscellaneous application seeking his detention for 21 more days, arguing that additional time is crucial for completing investigations, conducting forensic analysis on seized electronic devices, and preventing witness interference. An affidavit from senior IPOA investigations officer Abdirahman Jibril alleges that Talaam planned, directed, and attempted to cover up the fatal assault on Ojwang, and was in constant contact with Police Constable James Mukhwana, who had access to the cells. Talaam’s lawyer has opposed the application, citing the officer’s cooperation and 29 years of service, requesting bail, and pledging that Talaam would avoid the vicinity of Central Police Station if released. The prosecution, supported by the deceased’s family lawyer Julius Juma, insisted on the 21-day detention due to the case's complexity.

Police Constable James Mukhwana, identified as a key suspect, has provided damning details in the ongoing probe. Initially, Mukhwana admitted to not disclosing the truth when first summoned by IPOA on June 11, believing his colleagues would cover for him. However, upon realizing he was being scapegoated, he decided to reveal the truth, presenting himself to IPOA on June 12 where he was subsequently arrested and taken to Capitol Hill Police Station. In a subsequent statement to Abdirahman Jibril, Mukhwana confessed that Albert Ojwang was not intended to be killed but merely disciplined, as per instructions received from OCS Samson Talaam. He further claimed that Talaam had himself received instructions from Deputy Inspector General Eliud Lagat. Mukhwana also alleged that Talaam warned him against defying orders, emphasizing the ease with which junior officers could be dealt with for insubordination. Following these alleged threats, Mukhwana admitted to giving KSh 2000 to a remandee named Ngige to recruit inmates to assault Ojwang, also providing them with alcohol to facilitate the act. He then left Constable Kimani in charge of cell duties after Ojwang was brought in and confessed to deleting evidence after being warned not to speak on the phone. Mukhwana expressed remorse for Ojwang's death and is currently detained at Capitol Hill Police Station until June 20.
