Vigil after police kill unarmed teen turns ugly

Rioters looted and burned shops, vandalised vehicles and taunted riot police who tried to block access to parts of a predominantly black suburb of St Louis after a candlelight vigil for an unarmed man who was fatally shot by an officer turned ugly.

Streets in Ferguson were upended in the Sunday night riots and police made 32 arrests.

TV footage showed streams of people carting bottles of alcohol from a liquor store, and video posted online by the St Louis Post-Dispatch showed a convenience store on fire.
