Tear gas attack on subway

Authorities in Montreal are checking surveillance videos to try to identify the perpetrator of a tear gas attack at a busy Metro stop that left about 175 people with irritated eyes and throats.
The attack filled the Berri-UQAM subway station with the irritating gas, police said.

Most of those hit with eye or throat irritation and respiratory problems were quickly treated and released, but more than 10 were kept in hospital.

Police arrived quickly to help evacuate Metro riders, spokeswoman Brigitte Barabe said.
