Cochrane RCMP have arrested and charged four people in connection with a fire that completely destroyed the Chief Chiniki restaurant in August.

Police have arrested an adult and three youths who are all residents of the Stoney First Nation.

They say they have all been charged with arson.

RCMP say the adult is 20 years old, two of the youths are 16, and the third youth is 13 years old.

The identity of the adult arrested in connection with the blaze will not be released because police say it could reveal the identities of the three young offenders.

An estimated $1.1M in damage was caused to the restaurant, which was a popular destination for locals as well as travelers on the Trans Canada highway.

One of the accused will appear in a Calgary court on Friday while the other three offenders will appear in Cochrane Provincial Court on Nov. 27 and Nov. 29.
