The board of directors at Glentoran Football Club say they recognise performances have fallen below "what is acceptable to the club and our fans" and that it is their duty to "address this urgently".
In a statement released on Sunday evening the directors also condemned "incidents of violence, criminal damage and threats of harm" which they say occurred following the Glens 1-0 defeat to Larne at The Oval on Saturday.
While the club said they understood the frustration and concerns of fans, they said they would "act decisively" if they find individuals involved in violence, threats of harm or criminal damage once CCTV had been reviewed and statement had been taken from people present.
