Everton supporters have been accused of vandalising Anfield during Sunday's Merseyside derby defeat to Liverpool.
The Toffees edged a step closer to relegation after suffering a 2-0 defeat to their rivals across Stanley Park.
Second-half goals from Andy Robertson and Divock Origi secured a crucial victory for Liverpool, who are back to within a point of Premier League leaders Manchester City.

Meanwhile, Everton are now two points adrift of safety with just six games remaining in their season.
Seven yellow cards were handed out by referee Stuart Atwell, who at times struggled to control the ill-tempered match at Anfield.
The animosity between the two clubs spread into the stands, with Everton supporters accused of causing deliberate damage in the away section of the stadium.
Images circulating on social media show several TV screens smashed in the away end, with panelling and wiring ripped out of the roof of one of the toilets.
Speaking after the match, Everton manager Frank Lampard was frustrated with Atwell’s performance and believed his side should have been awarded a penalty when Anthony Gordon went down inside the area under pressure from Joel Matip.
“It is a penalty for me,” said Lampard, who has now lost all seven of his away matches as Everton manager.
“You don’t get them here. If that was Mo Salah at the other end he gets a penalty. I’m not trying to create conflict; it’s just the reality of football.
“I have played in teams in the top half of the league – you get them. That was a penalty for sure. It’s a clear foul.”
Everton are now two points behind 17th place Burnley, who have played one game more than the Toffees.
Lampard’s side return to action against Chelsea at Goodison Park on Sunday.
