A GRIEVING father has been given a restraining order to stop him contacting a man who was with his son when he died of a heroin overdose.

Robin Hussey’s 20-year-old son, Leon, died on New Year’s Day, 2010, at the family’s home in Stratton Way, Abingdon.

Greg Osbourne and Emma Langley were with Leon when he died and they woke Mr Hussey, magistrates were told.

After the inquest into his death, Mr Hussey tracked down Mr Osbourne to a house in Wantage, delivering a letter described as threatening in court on the anniversary of his son’s death.

But Mr Osbourne did not live there and instead the house belonged to his mother, Tamzin. She called the police after a second letter from Mr Hussey in May, magistrates were told.

Mr Hussey was due to appear at Oxford Magistrates’ Court earlier this month, charged with the harassment of Tamzin Osbourne, but the charge was dropped the day before.

Instead, the magistrates gave him a restraining order not to contact, directly or indirectly, Greg or Tamzin Osbourne for two years.

Warwick Clarke, defending, told magistrates: “Mr Hussey was woken at 5am by two people who had come into his house unbeknown to him with his son.

“They woke him to say your son died in the house. They said he had been dead for 30 or 40 minutes and could not explain why Mr Hussey had not been woken earlier.”

He added: “The inquest did not resolve the issue as to exactly how this happened.

“What (Mr Hussey) tried to do, and he concedes he has done this in a way that should not have occurred, was contact Greg Osbourne and understand how this death occurred.”

Mark Moorcraft, prosecuting, said: “Having spoken to Greg and Tamzin Osbourne, they appreciate it was unfortunate background but that still does not excuse Mr Hussey from sending letters of a threatening nature.

“What they really want is to put a stop to the threatening things in the future.”

After the court case, Mr Hussey, 56, said: “It has absolutely destroyed me and this fight is the only thing I have got in me.

“Otherwise I do not think I would be here any more.”

An inquest at Oxfordshire Coroner’s Court in September 2010 and recorded a verdict of accidental death.

Coroner Nicholas Gardiner said Leon died at his home having consumed alcohol, adding: “He had an injection of heroin, of which he was a naïve user”.

Police arrested Mr Osbourne and Miss Langley, who was also with Leon that night, at the scene on suspicion of supplying Class A drugs but they were released without charge.

Detective Inspector John Turner, from Oxford CID, said: “While I recognise Mr Hussey’s dedication to finding answers about the death, there is no further evidence to support any criminal prosecution.”

He has met Mr Hussey twice this year to review the investigation.
