Coast Regional Commissioner Rhoda Onyancha said there were no new arrests so far, and the total number of people arrested remains at 37, including the cult leader Paul Mackenzie, the Kenyan broadcaster said.
In April, local media reported four people had starved themselves to death, as Mackenzie had preached they would "meet Jesus" that way. Another 11 cult followers were hospitalized.
Shortly after, Mackenzie was arrested. In May, the Kenyan prosecutor's office said he would be charged with terrorism.
The affair shook Kenyans and compelled President William Ruto to form a task force to review laws controlling religious organizations as well as a commission to investigate the killings.
In June, Kenya's Interior Cabinet Secretary Kithure Kindiki announced the plans to transform the Shakahola forest, a scene of tragedy, into a national memorial site. The forest is expected to be turned into a place of "solace and remembrance for those affected" after the rescue operation and the recovery of bodies is finished.
