The arrest is part of ongoing efforts by the commission to tackle corruption within public institutions, especially among law enforcement officers.
In a statement released on Friday, the EACC said Sergeant Gilbert Kiama Oduor was arrested on January 28, 2026, after investigations into a complaint filed by a member of the public.
The complaint claimed that the officer demanded money in exchange for helping secure the release of a relative who had been arrested.
According to the commission, the case began on January 23 when police officers from Mamboleo Police Post, led by the area chief, carried out a raid at the home of a man identified as John Oluoch.
The raid was based on allegations that Oluoch was in possession of bhang.
However, the EACC said that no illegal substance or any other contraband was found during the operation.
Despite nothing being recovered, Oluoch was arrested and taken to Mamboleo Police Post, where he was booked.
His family later followed up on the matter, seeking clarity on why he was being held and what would happen next.
The EACC stated that during these follow-ups, the family was directed to Sergeant Oduor.
It is at this point that the officer allegedly demanded Ksh.15,000, promising that if the money was paid, Oluoch would not be taken to court and would instead be released.
Disturbed by the demand, the complainant reported the matter to the EACC, which launched investigations. After gathering evidence, the commission moved in and arrested the officer.
The EACC did not immediately disclose whether the money had been fully paid or the exact circumstances of the arrest, but confirmed that the operation followed standard investigative procedures.
The commission said the arrest sends a strong message that corruption, especially abuse of power by public officers, will not be tolerated.
It noted that police officers are entrusted with upholding the law and protecting citizens, and any officer found using their position to exploit the public will face the law.
Members of the public have been encouraged to report cases of bribery and corruption, assuring them that their complaints will be handled confidentially.
The EACC said public cooperation is key in the fight against corruption.
