The death of George Floyd, an unarmed black man who said he couldn’t breathe as his neck was knelt on by a Minneapolis police officer, has sparked protests all over the country. As they gained traction, so did online hoaxes and disinformation about them. BuzzFeed News is keeping a running list of the false and misleading information.

Before passing on any online rumor, take the time to verify it. This can be done by checking how recently an account has been created, keeping a close eye on information from news outlets, or searching online to find another source.

The person behind the account told BuzzFeed News in a direct message that they did not expect the tweet to get so much traction.

“I apologize to everyone that I potentially worried or caused any work to help find my ‘missing brother’ and that I never intended it to get such a wide range of people finding it from the start of my tweet,” he said. He declined to reveal his identity except to say he’s 16 years old and living in the US.
