Angry Leicester fans turned on the club's board after they were thumped at home by dominant Brentford.
The Foxes suffered a sixth straight Premier League home defeat without scoring - the longest ever run by a top-flight side within a single season - as goals from Yoane Wissa, Bryan Mbeumo, Christian Norgaard and Fabio Carvalho eased the Bees to victory.
Leicester supporters chanted against director of football Jon Rudkin and vented their fury with 'sack the board' as the club's survival hopes suffered another damaging blow with a 10th defeat in 11 games.
Boss Ruud Van Nistelrooy has won just two of his 13 league games since his November appointment, with his struggling side second bottom and two points from safety.
The Foxes have now not scored at home in the league for 75 days and Jamie Vardy was twice denied by Brentford keeper Mark Flekken early on, but there was little other promise once Thomas Frank's men took control.
The first goal after 17 minutes from Wissa followed muted chants for the removal of Rudkin, but the growing number of empty seats at the King Power made more of an impression, including the mass walkout of fans after the Bees added to their tally.
The dissent grew louder when Mbeumo curled in a 27th-minute second and Norgaard nodded in a third five minutes later as Brentford, who climbed to 10th, ripped through the hosts en route to sealing back-to-back league wins for the first time this season.
Kevin Schade headed against the post and Keane Lewis-Potter's disallowed goal for handball denied the Bees a fourth before the break.
Mads Hermansen's fine save then thwarted Yehor Yarmoliuk in the second half, but substitute Carvalho finally added a fourth from close range with a minute left as the visitors claimed a league double over Leicester for the first time since the 1952-53 campaign.
