Other fans tried to console Şen after his breakdown in the 43rd minute of the game. Florent Johan Malouda replaced the midfielder, who was unable to continue the game.
Three spectators have been detained in connection with the incident. They were released after being interrogated at a police station.
Commenting on the incident, Trabzonspor Chairman İbrahim Hacıosmanoğlu said that Şen's behavior was not becoming of a professional player.
“Swearing at players is unacceptable. It is impossible for us to accept such a thing, but it [walking off the pitch] was not becoming of a professional football player,” he said, calling the act childish.
