Metro Vancouver transit police are investigating an incident involving offensive language on a SkyTrain in Burnaby.
A video of the event was posted to Facebook, and as of Wednesday afternoon had been viewed 172,000 times.
It happened Monday afternoon around 2 p.m. PT on a Millennium Line train headed towards VCC-Clark station.
Transit police spoke to a witness who said a woman was swearing at an elderly couple on the train, before exiting at Holdom Station.
After checking surveillance footage, they determined that the woman used profane and racially slanted language.
The officers spoke with the elderly couple, who said they were fine and didn't want to involve the police.
The suspect has been identified by transit police as a 75-year-old New Westminster resident, who is known to police for anger-related issues in the past.
Transit police say the suspect will be interviewed and warned about her behaviour, but that there is no concern for public safety.
