Police used mobile phone footage to prosecute a husband for sexually abusing his wife even though she refused to give evidence against him.
Cy Cooper, 44, was pulled out of the address on Bluebell Close in the early hours of Wednesday, 29 July, following a fire at the property, but was later pronounced dead at the scene.
The results of the post-mortem examination determined the cause of Mr Cooper's death was multiple injuries, none of which were related to the fire.
A murder investigation has been launched by detectives and five people, four men and a woman, were initially arrested on suspicion of murder.
A 23-year-old man remains in police custody today being questioned by officers. The remaining four have been released from the investigation.
