The phone call came in around 11:30 Monday morning,from a male caller who claimed he'd killed several people and was holding several more hostage in a house in the 27100 block of 16 Avenue in Aldergrove.
Langley RCMP cordoned off the area.
Members of the Lower Mainland District Emergency Response Team (ERT) moved in with police dog services.
Paramedics were on standby.
At first, no one responded to a police loud hailer.
Then a woman stepped outside around 12:38 p.m. and was arrested.
There were no bodies or hostages inside the house, she told police, only her two teenage children.
The call was a hoax.
When the teens followed their mother outside, they were arrested for public mischief.
Police are now investigating the possibility the family computer was hacked by the actual person who made the prank call.
At the request of the family, the computer has been seized by for examination by the RCMP Tech Crimes Unit.
