KITCHENER, Ont. -- A 58-year-old man is charged with first-degree murder in connection with a deadly house explosion in Kitchener, Ont.

Waterloo Region Police say Udo Haan was arrested on Monday -- nearly six weeks after the explosion that rocked a quiet residential neighbourhood in August.

The blast levelled one home and caused extensive damage to some nearby residences.

The body of 58-year-old Edresilda Haan was found in the backyard of the destroyed home and her death was ruled a homicide.

Udo Haan, who family members previously identified as Edresilda Haan's husband, was seriously injured in the blast and police say he remains in hospital to this day.

Police did not say how many charges the accused is facing in relation to the explosion, but say they include one count of first-degree murder and one count of arson with disregard for human life.

They say the investigation into the incident is ongoing.
