In recent big games at Griffin Park supporters have brought flares in to the ground and lit them in The BIAS Stand, at the Ealing Road end of the ground.
This is a very dangerous action which puts the safety of the holder of the flare and those around them at risk.
The Club has received a letter from the Football League asking for an explanation as to why a flare landed on the pitch during the match against Portsmouth on April 13.
Supporters have also contacted the Club to complain about the act and football authorities have stressed that they do not want to see flares in football grounds.
A flare was lit during the FA Cup with Budweiser tie against Chelsea.
The person responsible was found by the Club and has been banned from Griffin Park.
The Club also has information about the person responsible for the flare against Portsmouth.
When they are caught, they will be banned from Griffin Park.
Anyone caught with a flare at Griffin Park tomorrow or at any other game will be ejected from the ground and face a banning order.
All at Brentford Football Club are looking forward to Bees fans enjoying a sold out Griffin Park with an electric atmosphere and making it a day to remember.
