Police in Canada have warned of the risk of copycat attacks after a deadly shootout in Montreal left three people dead, and a 104-page manifesto linked to the gunman was published online.
The document, later posted in full, contains racist and misogynistic conspiracy theories along with many of the familiar grievances associated with the so-called incel movement. Authorities said the text was allegedly encouraging citizens to shoot police officers, prompting Canada's federal police to send a bulletin to agencies across the country urging officers to remain highly vigilant and exercise extreme caution.
