Objects thrown at Ivory Coast's Eboue at Turkish game
Galatasaray's Ivory Coast defender, Emmanuel Eboue, was repeatedly pelted with objects during a Turkish football league derby at Besiktas.
Besiktas fans also shouted abuse at Galatasaray midfielder Engin Baytar during Sunday's game.
Video footage showed former Arsenal player Eboue being repeatedly hit on the head with objects, including a lighter and plastic water bottle.
Turkey's football federation has yet to comment on the incident.
Some reports had suggested there was a racial element to the abuse but Emek Ege, a sports presenter for NTV in Turkey, insists this is not the case and pointed out throwing of objects is common-place at Turkish matches.
Ege said that the Besiktas fans reacted angrily because they felt Eboue was feigning injury in order to waste time.
Besiktas officials also denied that racism was behind the rubbish throwing.
"The treatment Emmanuel Eboue was given by Besiktas fans on Sunday has nothing to do with racism," Besiktas spokesman Mete Duren said.
"Similar treatment was given to a Turkish player during the game as well, the sole motivation for the act was Eboue's theatrics aimed at deceiving the referee."
Besiktas could be fined by the Turkish football federation or indeed other sanctions for failing to control their supporters.
Sunday's game is the first to be played since a decision was taken that away fans will not be allowed to go to matches among Turkey's big four sides - Galatasaray, Besikitas, Fenerbahce and Trabzonspor.
In April Turkey also introduced stringent anti-hooliganism laws, including prison terms, for unruly fans.
