Three people were injured in an incident Friday morning in Aldergrove, Langley RCMP say.

At about 8:20 a.m., the Mounties arrived at a home in the 26600 block of 29th Avenue and found that all three people had superficial knife wounds.

Only two of the victims required medical treatment, said Cpl. Holly Marks, the Langley RCMP spokesperson.

All three people are known to police, and they all know each other, Marks said.

Police are investigating, but without much help from the three wounded people.

“At this time the individuals are not overly cooperative,” Marks said.
