A man who beat a drinking partner to death with a whisky bottle after insults were hurled about his dead mother was jailed yesterday for six years. Davinder Singh, 27, showed no reaction as Mr Justice Thomas Gall passed sentence in the Court of First Instance. Singh earlier pleaded guilty to the manslaughter of Harbans Singh, 49, whose battered body was found in his uncle's North Point flat on April 22 last year. The cause of death was a combination of a brain haemorrhage and head and neck trauma. The court was told the dead man's uncle, Gurcharanjit Singh Sandhu, had heard the two men arguing the night before the body was found. He also saw Singh strike the dead man's head several times with a whisky bottle. Defence counsel Keith Oderberg had told the court his client's violent outburst was at odds with his personality. He said Singh had lost control when Harbans Singh delivered a tirade of insults against his dead mother. Mr Justice Gall described the incident as a 'savage attack'. 'It was an attack upon someone who was until that evening a stranger to you,' he said. Mr Justice Gall said he adopted a sentencing starting point of nine years which was discounted to six years in consideration of Singh's early plea of guilty. Singh had earlier faced a murder charge.
