Liverpool supporters have set off flares in close vicinity to the team's Anfield stadium ahead of the Champions League clash against Roma.
The club issued a plea to fans ahead of the game, warning them that they could face arrest if they use pyrotechnics near the ground.
Images posted on social media and footage broadcast by Sky Sports News appears to confirm that smoke bombs were set off around Arkles Lane, a road the away coach is due to travel along.
A heavier police and steward presence is out in force for the Roma game.
