'He helped all his life': Jasna Badzak on the loss of her son Sven

Stabbing of 22-year-old in London prompts outpouring of grief and concerns about crime as lockdown ends

Sven Badzak had asked his mother, a doctor, to teach him first aid in case someone collapsed in the street after a heart attack or a stabbing. He never knew he would end up being a victim himself.

The 22-year-old became one of two people to lose their lives in violence in London this weekend, prompting the prime minister to say he was concerned about a rebounding" of crime figures as lockdown ends. Fourteen others were wounded in a spate of seven unconnected stabbings on Friday and Saturday.
