The English Football Association has launched investigations into two separate coin-throwing incidents at Premiership matches over the weekend.

The FA will be speaking to West Ham after Arsenal striker Robin van Persie was struck by a coin at Upton Park, and to both Fulham and Everton after midfielder Claus Jensen was hit by a coin thrown by an away fan at Craven Cottage.

A FA spokesman said: "We will be looking at the referees' reports and speaking to the relevant clubs to see what steps they are taking to identify who is responsible.

"The key thing is to identify those responsible and make sure they are dealt with appropriately."
