The Rolling Stones are keeping the flame of rock rebellion burning.

A London concert venue was given a warning Wednesday after members of the band were pictured smoking onstage during the first British date on their Bigger Bang tour.

Newspaper photographs showed Keith Richards and Ron Wood holding lit cigarettes during the show Tuesday at the O2 Arena.

Smoking is banned in enclosed public places in England under legislation that came into effect July 1. Companies that allow the ban to be breached can be fined up to $5,000.

Greenwich Council, the local authority for the southeast London area where the arena is located, said no one had complained about the onstage smoking, but the venue had been warned not to let it happen again.
