After the gun attack that killed ten in Buffalo, New York, the FBI is investigating suspected racist motives. “We are investigating this case for both a hate crime and a case of racially motivated violent extremism,” Buffalo FBI investigator Stephen Belongia said at a news conference on Saturday (local time). An armed attacker opened fire in a grocery store, killing ten people.

According to a report in the local newspaper The Buffalo News, three other people were injured in the act of violence, two of them very seriously. According to the report, the attacker wore a bulletproof vest and helmet and opened fire with a “powerful rifle”. Since the shooter was equipped with a camera, the police are checking whether the act of violence was broadcast live on the Internet.

According to the Buffalo police, the perpetrator was arrested. The police had previously announced via the online service Twitter that several people had been shot.
