Arsenal midfielder Emmanuel Frimpong has been charged by the English Football Association with improper conduct for allegedly posting anti-Semitic comments on Twitter.

The FA says Frimpong used a “reference to ethnic origin, faith or race” in response to an abusive tweet aimed at him on Sunday. The post has since been removed.

In a statement on its website, the FA said Tuesday that Frimpong is suspected of posting comments “amounting to improper conduct and/or which brought the game into disrepute.”

The football body gave Frimpong until July 27 to respond to the charge.

The 20-year-old player is recovering from knee injury while on loan at Wolverhampton Wanderers.
