OTTAWA, Ontario (AP) — Police aggressively pushed back protesters in Canada’s besieged capital on Saturday, towing away trucks, arresting dozens of protesters and finally retaking control of the streets in front of the country's Parliament buildings. Scores of trucks left under the increasing pressure, raising authorities’ hopes for an end to the three-week protest against the country’s COVID-19 restrictions and the government of Prime Minister Justin Trudeau.

The street in front of Parliament Hill, the collection of government offices that includes the Parliament buildings, was the heart of the protests. It had been occupied by protesters and their trucks since late last month, turning into a carnival on weekends.

“They are trying to push us all away,” said one protester, Jeremy Glass of Shelburne, Ontario, as authorities forced the crowds to move further from the Parliament buildings. “The main camp is seized now. We’re no longer in possession of it.”

Canadian authorities also announced they had used emergency powers to seize 76 bank accounts connected to protesters, totaling roughly $3.2 million ($2.5 million U.S.).

On Saturday, they also closed a bridge into the nation’s capital from Quebec to prevent a renewed influx of protesters.

Police said protesters remained aggressive, and pepper spray had been used to protect officers.

Around midday, protest organizers said they had ordered truckers to move away from Parliament Hill, decrying the police's actions as “abuses of power.”

“To move the trucks will require time,” organizers said in a statement. “We hope that (police) will show judicious restraint."

Earlier, Ottawa police addressed the protesters in a tweet: “We told you to leave. We gave you time to leave. We were slow and methodical, yet you were assaultive and aggressive with officers and the horses. Based on your behavior, we are responding by including helmets and batons for our safety."

Police said one protester launched a gas canister and was arrested as they advanced.

At least 47 people were arrested Saturday, police said. More than 100 were arrested Friday, mostly on mischief charges, and nearly two dozen vehicles had been towed, including all of those blocking one of the city’s major streets, authorities said. One officer had a minor injury, but no protesters were hurt, interim Ottawa Police Chief Steve Bell said.

Those arrested included four protest leaders. One received bail while the others remained jailed.

Tow truck operators wearing neon-green ski masks, with their companies’ decals taped over on their trucks to conceal their identities, arrived under police escort and started removing hundreds of big rigs, campers and other vehicles parked shoulder to shoulder near Parliament. Police smashed through the door of at least one camper before hauling it away.

The crackdown on the self-styled Freedom Convoy began Friday morning, when hundreds of police, some in riot gear and some carrying automatic weapons, descended into the protest zone and began leading demonstrators away in handcuffs through the snowy streets as holdout truckers blared their horns.

The capital and its paralyzed streets represented the movement’s last stronghold after weeks of demonstrations and blockades that shut down border crossings into the U.S. and created one of the most serious tests yet for Trudeau. They also shook Canada’s reputation for civility, with some blaming America’s influence.

The Freedom Convoy demonstrations initially focused on Canada’s vaccine requirement for truckers entering the country but soon morphed into a broad attack on COVID-19 precautions and Trudeau’s government.

Ottawa residents complained of being harassed and intimidated by the truckers and obtained a court injunction to stop their incessant honking.

Trudeau portrayed the protesters as members of a “fringe” element. Canadians have largely embraced the country’s COVID-19 restrictions, with the vast majority vaccinated, including an estimated 90% of the nation’s truckers. Some of the vaccine and mask mandates imposed by the provinces are already falling away rapidly.

The biggest border blockade, at the Ambassador Bridge between Windsor, Ontario, and Detroit, disrupted the flow of auto parts between the two countries and forced the industry to curtail production. Authorities lifted the siege last weekend after arresting dozens of protesters.

The final border blockade, in Manitoba, across from North Dakota, ended peacefully on Wednesday.

The protests have been cheered on and received donations from conservatives in the U.S.
