Flare lit in Wanderers bay at A-League GF

A flare has been ignited in Western Sydney's active supporter bays at Sunday's A-League grand final.

The device was let off amid the throng of about 10,000 travelling Wanderers supporters moments before kick-off at Adelaide Oval, though nearby police did not appear to respond.

The Wanderers were handed a suspended three-point deduction by Football Federation Australia in February after ongoing violence problems with their fan group, including one incident in which 19 flares were lit simultaneously in the crowd.
