On January 11 a Burundian radio station reported that a group of armed ex-FDD combatants in Kayogoro had begun “nighttime patrols” in mid-December, visiting houses and threatening residents who were not CNDD-FDD members.[102] Human Rights Watch received subsequent reports that participants were armed with guns and grenades and carried out illegal arrests of suspects, who were detained in Bigina zone—not an official jail—before being freed or transferred to police custody.[103]
