Cape Town - A young woman sat with her dead teenage brother as rubber bullets and teargas were allegedly fired at a crowd of Hanover Park residents baying for the blood of a man they thought was behind the young man's murder.Stones were hurled at the police in Rywood Walk shortly after the death of Reagan Jaggers, who was gunned down when he stepped out of his Erie Court home to investigate after hearing a shot fired nearby.Officers on the hunt for Jaggers' killers had arrested a man wanted for a separate murder and had pulled up near the family's home when a resident claimed the man in custody, seated in the back of the police van, had been the one who had shot "Chiney"."After that, it was chaos," Jaggers' sister Manecere told News24."People who had known my brother - neighbours, grown women, friends, everyone - stormed at the vehicle, wanting to get the man out. It was like a riot."WATCH: Gangsters shoot at police in Cape TownAll the while, she sat next to Jagger's body as the investigation of the crime scene was temporarily suspended.Police spokesperson Lieutenant-Colonel Andre Traut said, during the "altercation" with residents, the suspect identified for the murder managed to escape.'Still alive'An officer was hit with a stone and another was bitten during the attack.Traut said action was taken to prevent injury to the police members, but would not confirm if the crowd was sprayed with teargas or shot with rubber bullets as they had claimed, saying these details would form part of the investigation.A video, capturing the officers running away as men approach them, also circulated on social media platforms on Tuesday.READ: Cape Flats community keeps children safe from gang violenceShortly after 12:00, both Manecere and Reagan heard a single gunshot being fired."It was almost time for our baby brother to come home from school, so Reagan went to look what was happening outside. Just after he stepped out the door, I heard another shot, then someone shouting that 'Chiney' had been hit," said Manecere.Her mother was the first at the scene, followed closely by Manecere."He was still alive when I sat down next to him. He had been shot in the chest and his eyes were open, but he wasn't responding. I kept telling him, 'Don’t close your eyes; don't go'. But eventually, he did."'Couldn't believe he was dead'Jaggers' body lay there for four hours while police investigated and waited for pathologists."I just couldn't believe he was dead," Manecere said.Locals said they were shocked at Jaggers' murder, insisting he had not been involved in gangs or drugs."That is why we were so angry. This boy had done nothing to deserve what happened to him," one woman said.She did not want to be named as she had also thrown "one or two stones" at the police."I am a mother. I can't imagine what that woman is going through. Here in Hanover Park, you don't get justice when someone you love is killed. It gets added to a stack of unsolved cases, because there are too many gangsters and too little cops."The skollies can kill each other. Live by the gun, die by the gun - I don't care. But don't touch those who had nothing to do with your shit. Then you must pay."
