Exeter have banned two supporters from games at St James Park following social media abuse directed at departing midfielder Hiram Boateng and former manager Paul Tisdale.
Boateng recently signed for MK Dons – the club Tisdale left the Grecians for in June 2018 – and that news prompted a number of abusive messages on Twitter and Facebook.
An Exeter statement read: "City has today banned two supporters indefinitely from games at St James Park following social media abuse directed at both a former player and manager of our club.
"Exeter City takes a zero-tolerance approach to all forms of abuse, both at the ground and online, especially those of a discriminatory or racist nature.
"The posts, made on Twitter and Facebook, fall well below the standard we expect from our supporters and have been reported to Kick It Out and the police.
"The bans will take effect immediately, the length of which will be decided pending the conclusion of both a club and police investigation."
