A 19-year-old man has been charged with the murder of Antoin Akpom.
The news came last night, just ahead of a community event held to show support for the grieving families of Mr Akpom and Shehnila Taufiq and her three teenage children.
Mr Akpom, 20, died after being assaulted in Leicester on Thursday afternoon.
The bodies of Mrs Taufiq and her children, Zainab, 19, Bilal, 17, and Jamal, 15, were found in a burning house in the city shortly afterwards, in the early hours of Friday.
Police are investigating a possible link between the two incidents.
At the community event last night, Mrs Taufiq's husband, Dr Taufiq Sattar, and Mr Akpom's father, Ken, hugged and offered their condolences to each other.
Dr Sattar thanked "each and every" member of the audience "from all different communities", saying they had assisted him through a difficult time. He spoke of his "beloved wife", calling her "the best partner" and "very helpful and charitable".
He said: "She always greeted people with a smile, she had many friends and will be dearly missed."
Dr Sattar said his family had been "a pillar of support" for him.
Speaking of his loss, he said: "We are five in total, but now I am alone."
He said he got his strength from the love people had shown him since the tragedy on Friday.
Mr Akpom's uncle, Ronnie Akpom, who was joined by Mr Akpom's mother, Cheryl, and father Ken, spoke on behalf of his family.
He said: "Who would have imagined that only last Thursday two such tragic events could occur, resulting in the loss of five innocent lives and leaving a gaping hole in our lives?
"Our hearts are truly torn. The loss of Antoin for us has been immensely unbearable.
"Our worlds have been torn apart."
He said Mr Akpom was a popular and well-respected member of the community, adding: "The extent of his popularity has been brought home to us by friends and well-wishers over the past few days."
Mr Akpom was assaulted in Kent Street, off Humberstone Road, at about 5.30pm on Thursday. It is believed he collapsed in nearby Sussex Street before being taken to hospital, where he died.
On Friday, police arrested a 19-year-old in connection with his death.
Officers said last night the case had been reviewed by the Crown Prosecution Service, and it had been decided there was sufficient evidence to charge the man with murder.
The accused was held in custody overnight and was expected to appear before Leicester magistrates today.
Two men arrested in connection with the deaths of Mrs Taufiq and her children remained in custody last night.
The bodies of the four were found in a burning house in Wood Hill, Spinney Hills, after the fire service was called to the property at about 12.35am on Friday.
Officers said magistrates yesterday granted custody extensions in the case of two men, aged 49 and 19.
Meanwhile, police have swooped on a number of homes in the city as they continue to investigate all five deaths.
On Saturday, officers were at a home in Lake Chase View, Hamilton, while residents of St Matthews reported seeing a "massive police presence" there on Saturday night.
On Monday, detectives said they had identified a "significant witness" when they traced the driver of a BMW which was spotted being driven along Kent Street at the time Mr Akpom was assaulted.
Assistant Chief Constable Roger Bannister said: "There is a strong sense of determination and focus on bringing those responsible for both murders to account."
