The black man was killed in the US state of Louisiana, where 31-year-old Trefo was shot dead by police. A black man was shot 11 times by police.
Police say they received a report at 8pm that a man was trying to break into the store and had a knife in his hand. When police arrived on the scene, he fled and tried to break into another store, at which point police opened fire.
Tensions have risen again in the United States following the death of a black traffic policeman. Earlier, on May 25, a similar incident took place when a black man named George Floyd was killed by the police. The death of George Floyd triggered the McGuire movement, known as the "Black Lives Meter", which later spread throughout the Western world.
