Guns N' Roses have reportedly banned fans from wearing Slash merchandise.
According to TMZ, concert-goers at a recent show were told to remove their hats and turn their T-shirts inside out.
A member of the security team allegedly confirmed the reports and added that the orders came from one of the band's producers.
Some fans are said to have left the concert after hearing of the demands, although most reportedly decided to stay.
Slash recently insisted that he will never reunite with Guns N' Roses.
