The force said five men, aged 51, 52, 57 and 64, and a 47-year-old woman were arrested on Wednesday on suspicion of murder.

Those arrested are from the Sneinton and Bakersfield area of ​​Nottingham, he added, saying there would be a heavy police presence there as inquiries continued.

Assistant Chief Constable Rob Griffin said the force had received “numerous calls from the public” since the appeal was launched.

“Please continue to share our appeal and contact us with any information you may have,” he added.
