Face off, death threatening gang member out by its self

Hours after this dogs owner came for a face off with a chihuahua at the fence, saying my dogs will be eaten at next meet, the face off dog left the pack and came straight to me.
999 called.
The gang then went to fix my street , reporting I chased them for 15 minutes shouting
You are killing my dog ( now dead)
Taped 999 calls state otherwise.
