A female journalist was rushed to hospital after a flare was fired across the pitch into the stands during Wednesday's V.League 1 clash between Ha Noi FC and Duoc Nam Ha Nam Dinh FC at the Hang Day stadium.
Nam Dinh supporters ignited pyrotechnics throughout the match, showering the pitch with flares and causing the game to be interrupted multiple times due to safety concerns for the players and officials on the field.
The most serious incident, however, occurred when a roadside emergency flare was ignited in the 'B stand' and shot towards the 'A stand', directly hitting a woman's leg and forcing emergency services to step in.
