A stun grenade, also known as a flash grenade, flashbang, thunderflash or sound bomb, is an ostensibly non-lethal explosive device, used to temporarily disorient an enemy's senses. It is designed to produce a blinding flash of light of around 7 million candela (cd) and an intensely loud "bang" of greater than 170 decibels (dB). It was first used by the British Army's SAS in the late 1970s.
|Type||Non-lethal explosive device|
The flash momentarily activates all photoreceptor cells in the eye, blinding it for approximately five seconds. Afterwards, the victim sees an afterimage that impairs his or her aim. The loud blast temporarily deafens the victim and also disturbs the fluid in the ear, causing loss of balance. The concussive blast of the detonation can still injure, and the heat created can ignite flammable materials. The fires that occurred during the Iranian Embassy siege in London were caused by stun grenades.
Unlike a fragmentation grenade, stun grenades are constructed with a casing made to remain intact during detonation, containing most of its explosive force and avoiding fragmentation injuries, while having large circular cutouts to allow the light and sound of the explosion through. The filler consists of a pyrotechnic metal-oxidant mix of magnesium or aluminium and an oxidizer such as potassium perchlorate or potassium nitrate.
Stun grenades are usually designed to be non-lethal and cause no damage to the target. However, permanent hearing loss has been reported. Also, other injuries and deaths have been officially attributed to their use. These include the following:
List of incidentsEdit
- In 1989, police in Minneapolis, Minnesota, conducted a drug raid at the home of an elderly couple, Lloyd Smalley and Lillian Weiss, after receiving inaccurate information from an informant. The flashbang grenades police used in the raid set the home on fire. Police said they were certain no one was inside, and so, at first, made no attempt at rescue. Smalley and Weiss died of smoke inhalation.
- In May 2003, a woman named Alberta Spruill died from a heart attack after a police team detonated a stun grenade at her residence in Harlem, New York while looking for a drug dealer who was already in police custody. Her family eventually won a $1.6 million civil suit against the city.
- In February 2010, police in Minneapolis, Minnesota, raided the apartment of Rickia Russell looking for drugs. While Russell was eating dinner with her boyfriend, police threw a flashbang grenade after breaching the door. The exploding flashbang gave Rickia 3rd degree burns on both calves, and burns to her head. No drugs were found in Russell's apartment and the Minneapolis City Council agreed to pay $1 million in damages.
- In January 2011, a California man named Rogelio Serrato died of smoke inhalation after a flashbang grenade launched by a police SWAT team ignited a fire in his home. The man was believed to have been hiding in the attic when the fire broke out.
- In February 2011, a North Carolina SWAT police officer was injured at his home when a stun grenade accidentally detonated while he was attempting to secure his equipment. He underwent emergency surgery, but later died of his injuries.
- In January 2014, a man was severely injured during rioting caused by the 2014 Ukrainian revolution after he attempted to pick up a live, undetonated stun grenade. The grenade detonated seconds before he could reach it. The explosion caused damage to his right hand and arm, leading to the loss of most of his fingers, as well as heavy blood loss. As of February 2014, the man's condition was unknown. However, a video of it was uploaded to LiveLeak.
- On 28 May 2014 a 19-month-old baby boy's face was severely burned and mutilated when a stun grenade was thrown into his playpen by a SWAT team looking for drugs in his home in Cornelia, Georgia in the USA. The baby survived with facial disfigurement.
- On 3 August 2014 a Macedonian fan of the FK Vardar football team was seriously injured during a football match after trying to throw a stun grenade used by police when a fight between the police and the fans broke out in the stands of Stadion Tumbe Kafe stadium in Bitola. The grenade exploded in his hand causing him to lose two fingers and suffer severe damage to the structure of his arm.
- On 26 October 2014 Rémi Fraisse, a French botanist involved in nature conservation, was killed at 2 a.m. in Sivens Dam in Lisle-sur-Tarn, France by a French police flashbang at the age of 21.
