A 15-year-old girl has been charged after opera singer Katherine Jenkins was mugged in south west London while intervening in a street robbery.

Scotland Yard said the teenager was charged with robbery and assault on police after an incident on Kings Road in Chelsea.

Jenkins was mugged in south west London after she intervened in a "vicious" street robbery, her agent said.

The 39-year-old was on her way to a rehearsal at about 3.10pm on Wednesday when she witnessed an elderly woman being attacked.

After she stepped in to help, the singer was then mugged herself, her agent said.

The Welsh mezzo-soprano was in London to sing at the Henry van Straubenzee charity carol concert at St Luke's Church in Chelsea.

"Miraculously, Katherine still managed to perform at the concert as she didn't want to let the charity down," her agent added.
