Burnaby RCMP said they arrested 12 more protesters on Tuesday who were attempting to blockade a Kinder Morgan facility on Burnaby Mountain.

It came after a night in which protests became more aggressive, with one police officer sustaining a head injury from being kicked in the head, one being left with a knee injury and another a hand injury following a scufflie when four protesters were arrested, according to the RCMP.

One arrest happened after a male locked himself to an excavator that was on a flatbed truck. Removed from the excavator, he was held in contempt of a court-imposed injunction.

Another arrest happened after a female climbed atop the excavator and wouldn’t come down.

She climbed down herself following hours of negotiation. But then she was alleged to have resisted arrest.

Police later took her into custody. She, too, was held in contempt of an injunction, but police are still investigating her actions.

Numerous demonstrators tried to intervene while she was being arrested, police said. A male and female were later arrested for obstruction.

“In this instance, a group of demonstrators made a decision to protest unlawfully, our officers on scene dealt with an unfolding situation professionally and took action to ensure the safety of all involved,” said Supt. Chuck McDonald in a release. Tweet This

Terry Christenson told Global News he’d hoped that he would be able to stay in the tree longer, and was kept in jail overnight.

“All I’m saying is, yeah, there are conditions I signed, and we’ll take it from there. This isn’t over.”

Christenson, who is said he’s returning to his home in Ontario, is due back in B.C. for an April 9 court appearance.

There have been more than 60 arrests since Jan. 1.

The latest arrests came after Kinder Morgan was granted a permanent injunction to ban protesters from disrupting work at the Burnaby Mountain and Westridge Marine terminals on Mar. 15.

The expansion is set to increase the capacity of oil products flowing from Alberta to the B.C. coast from 300,000 barrels to 890,000 barrels.
