A Calgary man has been charged with second-degree murder in the death of his father.

Ranjit Rana Singh, 30, was arrested and charged on Friday in the slaying of Harinder Singh, 60, said Calgary police.

Emergency crews responded to a call of a man in distress at a home on Castleglen Way N.E. early on Dec. 7, 2009. The elder Singh died a short time later in hospital from injuries "sustained during an altercation" at the home, said a police news release.   

Police arrested the son two days after Singh's death but released him without any charges.

Last month, investigators issued an appeal to the public for help. They said the Singh family was not co-operating with their probe.
