West Ham fans have been warned by Essex Police after one supporter responded to defeat at Watford in rather extreme fashion.
A fan decided to call 999 after losing 2-0 to Watford on Sunday in David Moyes' first game as manager.
The Hammers have taken just one point from five games and are now perilously poised in the relegation zone.
In response to the 999 call, Essex Police tweeted: "Rinigng 999 because West Ham have lost again and you aren't sure what to do is not acceptable! It is a complete waste of our time."
Team captain Mark Noble urged unhappy supporters to get behind their struggling team after the loss, saying: "I know it's hard, I know they're frustrated, and we are too because we know we're better than what we're showing, but I urge them to stick by us and hopefully the good times will come back."
The Hammers, who have been in the top flight since 2012, have struggled ever since losing 4-0 to Manchester United on the first day of the season, forcing owners David Sullivan and David Gold to sack Slaven Bilic and replace him with Moyes.
West Ham host Leicester City on Friday in their first home match under their new manager, desperately hoping they can pick up three points.
