Two families have described their grief and devastation after the horrific events that left five of their loved ones dead.
Dr Taufiq Sattar has told how much he missed his 'beautiful' wife and three children, whose bodies were found following a house fire in Wood Hill, Spinney Hills, Leicester, in the early hours of Friday.
Police are treating te deaths of Shehnila Sattar and her three children, Zainab, 19, Bilal, 17, and Jamal Sattar, 15, as murder.
Last night police arrested a sixth person - an 18-year-old man - in connection with the investigation.
On Saturday, three women aged 19, 20 and 27 and two men aged 19 and 49 were arrested by detectives investigating the fire.
The 19-year-old man was released yesterday without charge but an extension for further detention was granted to police for the remaining four.
Dr Sattar said: "What has happened has happened and nothing can be reversed – but I hope justice prevails and, in future, this should not happen to any other family."
He attended his mosque near his home on Saturday and spoke publicly about the tragedy, thanking the people of Leicester for their support.
Police are investigating if the arson is linked to the murder of Antoin Akpom, who was attacked seven hours earlier in Kent Street, Highfields, on Thursday evening and died later in hospital.
They say there is no evidence that the Sattar family had anything to do with the incident in which Antoin was killed.
A 19-year-old man was last night being questioned by detectives in connection with the death of Antoin.
Two 19-year-old women who were arrested on Friday have been released without charge.
Yesterday, Antoin's family, including his year-old son, gathered at the football club where the 20-year-old, who hoped to become a teacher, used to coach youngsters.
They also visited the scene in Kent Street later in the day.
Antoin's uncle, Ronny Akpom, said: "An innocent life has been lost and the family calls for everyone to remain calm and united and assist the police with their inquiry so the people who did this are brought to justice."
During the weekend, forensic teams carried out searches at scenes. By yesterday afternoon, both cordons surrounding the crime scenes had been lifted.
Officers say they are continuing to investigate whether the two incidents are linked because of the close proximity of the crimes.
During a press conference on Saturday afternoon, Assistant Chief Constable Roger Bannister said: "Two families have been absolutely devastated and whole communities have been rocked by these two events.
"We believe that there are more people out there in the community who may well know who did this, who murdered the young man on Kent Street and who was involved in the fire on Wood Hill."
Anyone with information can call police on 101 or Crimestoppers on 0800 555111.
