West Bromwich Albion have vowed to take action against fans involved in the trouble at Villa Park on Saturday.

Seats were thrown from the Albion section and Villa supporters invaded the pitch twice during the game as Aston Villa beat the Baggies 2-0 on Saturday to reach the semi-finals.

Police have made 17 arrests related to the game and a spokesperson for the Football Association said its investigation into the incidents will begin on Monday.

Albion announced in a statement on Sunday that the apology had been "received in the spirit with which it was intended".

"West Bromwich Albion note the public apology issued by Aston Villa FC in the wake of the disturbing scenes during and after the FA Cup quarter-final at Villa Park," read the statement.

"The apology is received in the spirit with which it was intended.

"The club is also aware of reports of serious misbehaviour involving some of its own supporters.

"It issues an uncompromising reminder today that any supporter found guilty of disorder offences can expect the appropriate sanction from the club. West Bromwich Albion will continue to operate zero tolerance to any fans who bring the club's reputation into disrepute.

"The club also welcomes the FA investigation into the scenes and how they came about; West Bromwich Albion will co-operate fully.

"Pitch invasions cannot be tolerated under any circumstances. The safety of the club's players and staff during and at the end of the game was clearly compromised and that has to be a subject of deep concern for everyone involved."
