The fiancé of former X-Factor singer Jaymi Hensley has died after falling from a third-floor hotel window.

Oliver Marmon, also known as Olly, fell from a window at the Hind Hotel in Wellingborough, Northamptonshire.

Emergency services were called to the scene just after 11.30pm on Sunday, August 11, where the 33-year-old was pronounced dead.

Hensley was a member of boyband Union J, who featured on X Factor in 2012, Sky News reports.

He had posted on his Instagram account in September that the pair were due to get married later this year.

Sharing a photo of himself kissing Mr Marmon's cheek, Hensley, 34, wrote: "14 years together and 1 year until "I do". I love you irrevocably and so excited that in 365 days we will finally be Mr&Mr."

Police initially said they were investigating the death as murder but confirmed the probe had been closed following the results of a forensic post-mortem on Tuesday (August 13).

A 34-year-old man arrested in connection with the incident was released without charge, Northamptonshire Police said.

Detective Chief Inspector Johnny Campbell, who led the investigation, said: "This has been a complex and fast-moving investigation, and our thoughts remain with Olly's family and loved ones at this very difficult time.

"It is only right that an incident such as this is treated with the utmost seriousness, to make sure we have done all we can to understand what has happened, and to get the answers those left behind need and want.

"In Olly's case I can confirm the evidence we have examined did not support his death as a homicide, which has now been further confirmed by the results of the preliminary forensic post-mortem report.

"Our initial findings and decision have been explained to Olly's family, who will continue to be supported by Northamptonshire Police as they mourn the loss of their loved one."
