PRESTON, England, July 7 (UPI) -- A man who planned to kill his wife with a homemade electric chair after she asked for a divorce has been sentenced to 10 years in prison.

A judge in Preston Crown Court imposed the sentence this week on Andrew Castle, 61, The Sun reported Thursday.

Investigators said Castle wired the chair in the garage of the couple's bungalow in Poulton-le-Fylde on the Lancashire coast. He then brought his wife to the garage and asked her to sit down while they talked about the divorce.

When Margaret Castle got up, he hit her, but she escaped, running into the street screaming. Police found her husband with slashed wrists.

A source close to the investigation described the chair to the Daily Mirror: "It was not a sophisticated contraption, but it could have been very effective."
