Recent documentation from the Rio de Janeiro Civil Police illustrates the continued development of locally manufactured explosive devices in the state. In a video published on May 5, 2026, a specialist from the Rio de Janeiro Civil Police’s Bomb Squad displayed devices ranging from rudimentary pipe IEDs and bicycle-pedal-based improvised grenades to more refined improvised grenades, some of which he noted could initially resemble standard grenades.
Criminal organizations in Rio de Janeiro have long manufactured IEDs ranging from simple pipe IEDs to more refined improvised hand grenades, while recent police documentation shows these designs remain in circulation and continue to evolve. Armed UAV activity further demonstrates an expansion toward the aerial delivery of compact explosive munitions.
Technical studies by the Rio de Janeiro Civil Police Bomb Squad provide rare forensic insight into the construction, explosive fill, fragmentation, and initiation systems of the principal locally manufactured grenade families and help contextualize the grenade-type and PVC-bodied munitions now documented with UAVs used by different criminal groups.
