Two more men have been arrested in connection with an explosion in Leicester that killed five people.
Leicestershire Police said the suspects, who are both in their 30s and from East Anglia, were held on Friday.
They were detained on suspicion of conspiracy to cause an explosion, and for offences under the Proceeds of Crime Act, the force added.
Three other men, arrested on Wednesday on suspicion of manslaughter, are still being questioned. They are from the East Midlands, East Anglia and the North West.
Officers have refused to comment on reports that the blast, shortly after 7pm on Sunday, was caused by an illegal alcohol distillery.
The explosion was followed by a large fire. Once the flames were out, human remains were recovered from the ruins of the building, which contained a supermarket and a two-storey flat.
The victims have been named as Mary Rajoobeer, 46, and her two sons Shane, 18, and Sean, 17. Also killed were 18-year-old Leah Beth Reek, who was Shane’s girlfriend, and 22-year-old Viktorija Ljevleva.
Another five people were taken to hospital.
Specialist officers are continuing to sift through the wreckage. The scene is expected to remain cordoned off for several more days at least.
