Two police officers were bitten by girls in south London after they asked a 15-year-old girl to pick up her litter. One officer was dragged to the ground and kicked while the other was bitten by a girl who jumped on his back.
Police said the girl initially picked up the fast food wrapper when asked by the patrolling officers, but immediately dropped it again sparking the confrontation.
Both officers, aged 34 and 29, suffered bruising and knee injuries and the officer who received the bite wound required hospital treatment.
Police have been examining CCTV footage from the area.
