An investigation is under way into claims by Manchester City defender Gaël Clichy that a banana was thrown on to the pitch during his side's friendly win over Limerick.

The Gardai and stadium officials are studying CCTV footage in an attempt to identify a spectator alleged to have thrown the object on to the pitch during the Premier League champions' 4-0 victory at Thomond Park on Sunday.

A statement released on behalf of Limerick FC and Thomond Park Stadium said: "The Gardai and stadium officials are reviewing the CCTV recordings to attempt to identify an individual involved in the throwing of an offensive object on to 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."

It is understood that Manchester City made no formal complaint over the incident, which was mentioned by Clichy via his Twitter account.
