A stun grenade has been provisionally withdrawn from use after a serious incident. The device, known as the EF-SON, has been used by police since 2025. An incident involving the grenade resulted in a 15-year-old student suffering a severe injury, with his hand being torn off.

The EF-SON stun grenade was used by French police prior to its suspension. Details of the incident that led to its withdrawal are available from the source.
