The Emergency Response Team was called out to Aldergrove for the second time in a week on Friday, but found no guns and made no arrests.
At about 10:20 a.m., the RCMP officers began arriving at a property in the 26700 block of Fraser Highway after a report of multiple people with guns in the area.
The highway was closed for half a mile between 264th and 268th Streets, and numerous plainclothes and uniformed police established a command centre at the nearby Aldergrove Royal Canadian Legion.
The Lower Mainland Emergency Response Team (ERT) was called in, and brought their armoured personnel carrier, as well as officers wearing body armour and carrying high-powered rifles.
By about 1 p.m., however, the incident had ended with no arrests.
Police cleared at least one building, possibly more on the property, said Const. Craig Van Herk of the Langley RCMP.
Neighbours reported that a young woman had been taken away from the area, apparently hysterical, but Van Herk said he did not have information about her.
It is possible she simply tried to go back through the roadblock and was taken away for her own safety, he said.
At 12:18 p.m., a loud bang was audible for half a mile, but Van Herk said it was definitely not a gunshot. It may have been a distraction device set off by the ERT, he said.
The Langley RCMP Serious Crime Section is still investigating.
Police allowed traffic to begin flowing again just before 1 p.m.
