Three other men, aged 20, 24, and 28, were also stabbed in London in the past week. The London murder toll is now more than 65, putting the death rate on track to hit its highest annual total since 2003.

Figures published in April showed a 22-percent annual rise in knife crimes in England and Wales. Robbery rose by 33 percent and gun crime rose by 11 percent, while and murder increased by nine percent.

One of the victims of London's five-day stabbing spree died on Friday, three days after he was attacked in West London. Osman Shidane, 20, was described by his family as a selfless and caring man.

Shidane, born in Denmark but had lived in Britain for 15 years, was the eldest of seven siblings of Somali origin. He was stabbed in the neck and armpit as he walked along an alleyway next to a church. A 16-year-old boy has been charged with his murder.

"He was a family man, he was caring and compassionate," 17-year-old Nasteho, one of Shidane's five sisters, told the Evening Standard. "He was very outgoing and naturally got along with everyone."

Arunesh Thangarajah, 28, was stabbed to death in the early hours of Sunday morning, just before 3:30am in Mitcham. Police said that Manimaran Selliah, 44, a Mitcham resident, was charged with Thangarajah's murder.

Abrahaman Juma, a 24-year-old man was stabbed to death by a gang of youths on Thursday night in Barking. His uncle, Haroub, said: "He was a nice guy, a good person. I cannot put how I feel into words."

Juma's neighbours said that the pack of youths chased their victim Juma through the estate where he lived and attacked him.

Detective Chief Inspector Andrew Packer, who is leading the inquiry into Juma's murder, said: "I know there were people out and about in [the area] at the time of the murder. I need to speak with these people as soon as possible as they may have vital evidence."

Metropolitan Police commissioner Cressida Dick said last week that among the complex problems driving youth violence, there was also a reduction in the number of police officers. Home Secretary Sajid Javid is expected to address the issue at the Police Federation conference on Wednesday.
