Guns N' Roses threatened to walk off stage during their concert in London on Friday after fans took aim at the rockers with flying missiles.

The band wrapped up its controversial British leg of the tour on Friday night at the O2 Arena, but they almost cut short the set after being pelted with money and plastic glasses - the latest incident to mar the stars' U.K tour.

According to NME.com, bass player Tommy Stinson fumed at the crowd, "If you throw any f**king thing on stage, we'll go home."

Frontman Axl Rose added that Stinson was merely "laying down the law."

The rockers were also late on stage once again, appearing nearly an hour after their scheduled show time.

It's not the first time Guns N' Roses have come under fire from fans on their U.K. tour - angry concertgoers have been blasting the band for its constant tardiness and one fan claimed security staff at Thursday's O2 gig had ordered him to remove his T-shirt featuring ex-bandmember Slash or face being denied entry to the gig.

The rock icons will next play at Ahoy in Rotterdam, Holland on Monday.
