NBA fans were forced to leave the Chase Center in San Francisco on Saturday night after a fire alarm was extracted in the middle of the NBA game of the Warriors-Pistons.
The worrying scenes developed among the rooms when a terrifying message appeared on the huge screen on the court, urging fans to go to the exits.
The message said: 'Attention: a fire alarm has been reported in the building. Proceed at the nearest exit and leave the building. Do not use elevators.
The reporters who covered the game said that some fans immediately followed the instructions and rushed at the exit, while others stayed in their seats.
It is not yet clear if the alarm was a real test or incident, but the game continued shortly after, although some fans left the sand.
The sports reporter of the Bay area, Cam Inman, wrote in X shortly after the alarm ended that the '20 percent of the fans had left their seats for the exits', before they told them they could return.
A PA message for fans said: 'Fan attention, we have just received the full signal. You can return to your seats.
