Following events at today’s Exeter City v Carlisle United match in Sky Bet League 2, The Football League has issued the following statement.
The Football League's Chief Executive, Shaun Harvey, said:
"Both clubs, the matchday security staff, the emergency services and the overwhelming majority of supporters should be commended for their response to today's events.
"Unfortunately the actions of one individual have caused significant disruption and put fellow fans at risk of injury.
"The taking of smoke grenades or flares to football matches is irresponsible and absolutely mindless.
"It is something that has to stop."
