Two young Surrey girls were arrested following a series of stabbings along the SkyTrain line late Monday night.

"We don't have a motive at this point," said Transit Police spokeswoman Anne Drennan. "It appears to be random violence."

It started at 11:30 p.m., at Gateway Station in Whalley. Drennan said the two girls, ages 14 and 15, are well known to police. They confronted two women who were standing across a street from Gateway Station.

"It looks as though they were itching for a fight," Drennan said of the girls. The 15-year-old had an eight-inch-long steak knife.

After slashing one of the women on her forearm, the teens got on the train northbound and began menacing a woman passenger. Drennan said they threatened her while slashing a seat with the knife during their "tirade."

The frightened woman got off the train at Columbia Station and the girls followed her. When the woman turned, one of the girls punched her in the face, leaving her with cuts and scrapes.

The girls then caught the SkyTrain to Joyce Station, where they attacked a man with the knife. His finger was sliced as he defended himself with a pizza box, using it as a shield.

The girls then ran away. Drennan said police caught up with them a short distance from the station.

"It could have been much worse," she said of the victims' injuries.

Police are recommending that the girls be charged with assault with a weapon, assault causing bodily harm, threatening, and possession of a weapon dangerous to the public.
