Police say he appeared to intentionally strike pedestrians after mounting a busy pavement in a rental van. He was arrested several blocks away after a tense standoff with police.
Mr Minassian's Facebook post, which the social network has confirmed as real, praised Elliott Rodger, a 22 year old from California who killed six people in a shooting rampage through Isla Vista, California in 2014 before turning the gun on himself.
It read: "The Incel Rebellion has already begun! We will overthrow all the Chads and Stacys! All hail the Supreme Gentleman Elliot Rodger!" The term "incel" refers to a now-banned group on the message site Reddit, used by Rodger, where young men discussed their lack of sexual activity and attractiveness to women - often blaming women for the problem.
"Chads and Stacys" refers to attractive men and women who are perceived as better than or unavailable to "incels", which is short for "involuntary celibate".
