Everton's famous Dixie Dean statue was damaged after being lit with a flare, causing outrage across Liverpool.
Fans were left upset and angry after video footage of the incident outside Goodison Park was shared on social media throughout Monday afternoon.
The flare is believed to have been left on the beloved statue of the Blues legend in the early hours of Sunday morning before burning out and causing a small amount of damage.
Staff from the club cleaned the statue later in the day before contacting police and passing on vital CCTV footage.
Officers have now confirmed they are looking into the incident which was described as "disgusting" and "disgraceful" by supporters.
The site of the Dixie Dean statue on Spellow Lane has become synonymous with fans who often leave flowers and wreaths around it for loved ones who followed the club before passing away.
Video footage was shared online of the flare burning on the arm of the statue with dozens of floral arrangements lying underneath.
Responding to the video, supporters and police have called out those who are responsible for the incident.
One Twitter user, @TrickyTrev20 said: "This is disgusting. It's a place were people remember their loved ones.
"It's not even clever or funny. Just pointless."
