Police are investigating whether two separate shooting incidents within two hours last night are linked.
Two people admitted themselves to hospital with gunshot wounds at about 5pm yesterday.
They had allegedly been shot in Battersea's notorious Winstanley estate.
Earlier in the day, a man was killed and two others injured near to where a funeral was being held in East Dulwich. Both incidents are thought to be gang related and detectives are trying to establish a link between the two.
