The Surete du Quebec has relieved a second high-ranking officer from his duties over the handling of the Highway 13 closure this past week.
He is being reassigned to administrative functions.
On Tuesday hundreds were stranded for hours on the highway without any help.
The SQ launched an internal investigation into how the situation was handled. That investigation is ongoing.
Meantime, the Surete du Quebec has arrested one of two truck drivers who allegedly refused to cooperate with a towing operation during the snowstorm on Tuesday night.
