A YOUNG prisoner found hanged in a Dorset jail created an “intricate” ligature despite having only one arm, an inquest heard.

Michael James Devoy had been speaking on a smuggled mobile phone to his girlfriend hours before his body was found at Guys Marsh prison near Shaftesbury, Dorset coroner Sheriff Payne was told.

The Bournemouth inquest heard Mr Devoy, a 22-year-old father-of-three, was convinced his girlfriend was sleeping with another man.

A jury of five women and six men is examining the circumstances of Mr Devoy’s death at the inquest, expected to last up to three days.

Jurors heard that Mr Devoy, from Gloucester, was serving a nine-month sentence for assaulting his girlfriend, Lucy Phelps. He was transferred to Guys Marsh from a prison in Bristol on July 14 and was found dead a month later.

Outlining the case, Mr Payne said Mr Devoy was found hanged with a strip of bed linen from a light fitting in his single cell.

He said Mr Devoy had a total right arm amputation after suffering meningitis at the age of 16 but still managed the “intricate” process of creating the ligature and barring the door of his cell.

The inquest will hear from healthcare professionals about the state of Mr Devoy’s mental health.

When he was in prison in Bristol he was subject to ACT - Assessment Care in Custody and Teamwork - meaning that closer checks are made by prison staff. No such order was in place at Guys Marsh. Jurors will also hear evidence from prison staff and other inmates.

Addressing jurors, Mr Payne (inset) said: “Was an opportunity missed to save him? Was he correctly assessed? Was his death predictable?

“He was concerned about his relationship with the girlfriend that he had assaulted and the son that the two of them had. He was obsessed with the notion that Lucy Phelps was sleeping with another man.”

Mr Payne said Mr Devoy had two other children from a previous relationship. The inquest continues.
