They said the teenager, who was wearing a tag at the time he was killed on Monday afternoon, had once been 'badly behaved' but was getting his life back on track.
But they fear he may have been caught up in a 'postcode war' among rival gangs.
The first attack on Louis came at 11am. The second followed a youth offending team meeting in Battersea, where staff offered him a £50 Tesco voucher if he was home with his mother by 6pm.
So they "bribe" you to be good ??/ and he was on tag ??/........
