The Law Society of Kenya (LSK) and the Police Reforms Working Group have condemned recent cases of abductions during protests.
Media reports have highlighted incidents involving masked individuals threatening to infiltrate protests in Kapsabet town.
In a statement on Thursday, LSK and the Police reforms group also criticised the use of police force against protesters.
"Considering the protests planned for today, we call upon the National Police Service to refrain from the unlawful use of force, arbitrary arrest, detention of protesters, and forceful abductions," the organisations said.
The groups have urged security officers to protect protesters from interference by third parties.
"We call upon the Acting Inspector General of Police to refrain from deploying ununiformed or masked officers dressed in hoodies, balaclavas, or other attire that conceals their identities," the statement read in part.
The LSK has also condemned the use of tear gas and high-pressure water cannons on protesters. They noted that the use of force can affect bystanders, particularly given the ongoing school holidays. "Such use of force in residential areas is even more dangerous today as many children are on a school break," they said.
They further advised police to stop using unmarked vehicles or vehicles with distorted or no registration plates to commit crimes and evade justice during protests.
The working groups have condemned the harassment of leaders of Social Justice Centers by authorities attempting to intimidate them into withdrawing from the protests. By Sharon Wanga, The Standard
