The Saskatoon Police Explosive Disposal Unit and patrol officers responded to a home on Wentworth Crescent after Police, Saskatoon Fire and Protective Services and MD Ambulance all responded to a 9-1-1 call just after 8:30pm CST, Friday evening.

Another 20 year old man was in the basement when police arrived. He was also injured in the explosion.
