The father of a slain B.C. Lower Mainland gang member has been charged with threatening to kill children at a kindergarten or elementary school, CBC News has learned.

According to information sworn to obtain a search warrant for the home of Michael Denis LeClair, the 59-year-old allegedly expressed "a desire to use violence to take the law into his own hands and seek revenge for the death of his son."

Kevin LeClair was shot at a Langley shopping centre on Feb. 6, 2009. He was a member of the Red Scorpion gang, a criminal organization in the Fraser Valley allegedly headed by brothers Jarrod and Jamie Bacon.

Two men were charged in January 2011 with Kevin LeClair's murder, but fled prior to arrest and remain at large.

Michael LeClair is a retired RCMP officer. He was arrested last month and charged with uttering a threat to three leaders of a victim support group "to cause death or bodily harm to children in kindergarten and elementary school."

He has also been charged with seven counts under the Firearms Act in connection with the alleged possession of a shotgun and a Winchester 30-30 rifle.

The allegations contained in the search warrant are a police theory of the case and none has been proven in court.
