The building on which a mural of Colin Kaepernick was painted in Atlanta has been demolished on Super Bowl weekend.
Fabian Williams, the artist who painted the mural, posted a video of the site on social media on Friday, two days before Atlanta hosts Super Bowl 53.
NFL player Kaepernick started kneeling during the US national anthem in 2016 to protest against racial injustice.
Williams, who is also known as Occasional Superstar, said “the timing is mad suspicious”.
It is not known who was responsible for the demolition.
Kaepernick’s protest developed into a movement as many other NFL players followed suit and in May the NFL announced that teams would be fined if players continued to kneel during the national anthem.
