A woman has been killed in Montreal in Canada after her hair and scarf became entangled in a subway escalator, officials say.
The 48-year-old victim, whose name was not released, was riding on the moving staircase during her morning commute when the garment got snagged, police said.
"She tried to pull the scarf free but her hair got entangled and she was apparently strangled to death," a police spokesman said, citing witnesses and surveillance video.
Authorities, who said the woman died at the scene, are investigating the incident.
