Police are investigating claims a banana was thrown at Manchester City defender Gaël Clichy during the Premier League champions' 4-0 win against Northern Ireland side Limerick.
City played their final pre-season game ahead on Sunday ahead of this weekend's Community Shield encounter with Chelsea, and Gardai and Thomond Park staff are studying CCTV after Clichy alleged he was targeted.
The Frenchman said on Twitter:
Limerick also issued a statement, which read:
"The Gardai and stadium officials are reviewing the CCTV recordings to attempt to identify an individual involved in the throwing of an offensive object onto the playing field.
"Any individual identified as being involved in an incident of this nature will be banned from future attendance and the matter will be handed over to the Gardai.
"All those involved with the friendly game fully condemn all forms of unacceptable behaviour of this nature."
City have made no formal complaint, but last season they did report racist abuse suffered by Mario Balotelli and Yaya Touré during their Europa League fixture at Porto in February.
