PLAYERS and fans were urgently evacuated from Pride Park ahead of Derby's Championship game against Cardiff.
Players were rushed from the pitch during the warm-up as the PA announcer urged everyone in the stadium to leave.
Video footage shows players and staff from both teams sprinting off the pitch as the announcer's warning was played loudly on repeat.
The message said: "Attention please, this is an emergency. Please leave the stadium by the nearest available exit."
Fire exits around the ground were opened to allow fans and members of stadium staff to flee.
While there was no reason given for the emergency evacuation, fans and players were allowed back in around five minutes later.
There were reports of fans without tickets walking back in through the fire exits as supporters made their way back in.
