POLICE could launch an investigation after excrement was left in the Crystal Palace dressing room before Monday's clash with Brighton.
Ian Holloway's side received the grim greeting in the shower area at the Amex Stadium.
Palace had the last laugh - perhaps motivated in part by the dirty protest - as a brace from Wilfried Zaha earned them a 2-0 win and a place in the Wembley play-off final.
Brighton boss Gus Poyet was apparently so disgusted by the incident that he sent a furious e-mail to his staff, demanding to know who was responsible.
In the e-mail, Poyet allegedly calls for the perpetrator to be sacked while going on to slam the club's decision to give paper clappers to fans, calling it a "stupid idea".
Poyet has since been suspended by Brighton, though this is said to be in a row over the club's transfer budget and not necessarily connected to this incident.
