Three people are being questioned by detectives investigating a murder possibly linked to a fatal house fire which killed a mother and her three children.
Shehnila Taufiq, who was in her 40s, died along with her 19-year-old daughter and sons, aged 17 and 15, in the blaze at their home in Leicester in the early hours of Friday
The mother and her children, named by their local mosque as Zainab, Jamal and Bilal, died in their bedrooms at their terraced house in Wood Hill in the Spinney Hills area of the city, several hours after a man was killed in nearby Kent Street.
Police believe the family may have been killed in a revenge attack, which neighbours claimed could have have been a case of mistaken identity.
A man and two women, all aged 19, were arrested over the killing of the man in his 20s - named in reports as father-of-one Antoin Akpom. Police said the man was arrested in London.
Mrs Taufiq's neurosurgeon husband, Dr Muhammad Taufiq Al Sattar, was on Friday believed to be on his way home from Ireland, where he works in the Beaumont Hospital in Dublin and with private hospitals in the city, the Blackrock and Hermitage clinics.
Police have said they cannot rule out a link between the two events and they are investigating whether the fire was started intentionally as a revenge attack. Leicestershire Police have not yet confirmed the identities of the five victims.
The force launched its first murder inquiry shortly after 5.30pm on Thursday when a man in his 20s was taken from Kent Street - half a mile away from the scene of the fire - to Leicester Royal Infirmary, where he died. A second inquiry began when neighbours reported flames shooting out of the first floor of the Taufiq family home at 12.30am.
Assistant Chief Constable Roger Bannister said officers were investigating a theory that Mrs Taufiq and her children were killed in revenge for the earlier attack. He said: "I can't confirm here and now it is a revenge attack - it may be, it may not be - but lines of inquiry will certainly get to the bottom of that."
Urging witnesses to get in touch, he said it was possible that both offences, which he described as "terrible, terrible crimes", were linked.
