Three men have been arrested on suspicion of manslaughter after five people died in an explosion in Leicester, police have said.
Leicestershire Police have been investigating the cause of the blast, which happened at a Polish supermarket with two flats above it in Hinckley Road just after 7pm on Sunday.
The suspects are all in their 30s and were arrested on Wednesday evening, police confirmed.
One man comes from East Anglia, one is from the North West, and the other is from the East Midlands.
"No further details will be released about these individuals at this stage," said a police spokesman.
"We acknowledge that the terrible events of Sunday night in Hinckley Road have attracted significant public, political and media interest.
"However, in the interests of the ongoing investigation, and out of respect for the families of those missing feared dead, and those who were injured in the explosion and fire, we request that the media and public resist speculating about the identities of those arrested, the circumstances that may have led to their arrest and the cause of the explosion.
"Whilst we will not disclose further details at this stage, we stress that there remains no evidence that the events of Sunday night are in any way terrorist related."
Search and rescue teams found five bodies in the wreckage, but they were so badly injured police said "it may be some considerable time before the bodies can be formally identified".
Mary Rajoobeer, 46, and her two sons, Shane, 18, and Sean, 17, were named by police on Tuesday as missing following the explosion, as was Leah Beth Reek, 18, who was Shane's girlfriend.
Viktorija Ljevleva, 22, who is thought to have been working at the supermarket, was also reported missing.
Another five people were taken to hospital.
Shocking footage of the explosion was captured on CCTV, showing debris being blasted across the road to the opposite pavement.

The building was still on fire on Monday morning.
Search teams have faced continuous difficulties at the site, having to suspend work periodically due to concerns over the structural integrity of neighbouring buildings, as well as the wintry weather causing disruption across the UK.
