"The analysis of the complaint is ongoing and the conclusion of the investigation should follow in the coming weeks," said Frédéric Jean with the Laval police.
On October 6, municipal affairs minister Pierre Moreau made a funding announcement at Laval city Hall.
Outside, hundreds of municipal workers were staging a noisy protest against Moreau's pension reform bill, Bill-3.
As Moreau tried to leave in a black government SUV, the demonstrators were waiting for him.
A video posted on YouTube shows the SUV turn onto the grass beside city hall to avoid them.
It continues down a grassy hill as protesters follow and finally the SUV hops the sidewalk onto the road.
One of the demonstrators filed a complaint with police because bylaws in Laval prohibit vehicles from driving in parks or on green space.
He faces a fine of between $75 and $1,000.
Moreau's office has refused to comment.Suggest a correction
