Hibernian FC fans suspected of being involved in the Scottish Cup final pitch invasion have been sent letters from club officials putting their membership "on hold".

Supporters have been told they must contact the Edinburgh club to "discuss any involvement" in the disorder following Hibs' 3-2 win against Rangers at Hampden on May 21.

The letters, signed by football safety officer Robert McGregor, claim that he is in "possession of information" of which fans were on the pitch after the final whistle.

"The club understands that supporters were overjoyed to win the Scottish Cup, however we also recognise that anyone leaving their seat and going on to the pitch is a serious matter, amounts to unacceptable conduct and places those on the pitch and others at risk," he wrote.

"The purpose of this letter is to request that you make contact with me to arrange an appointment to discuss any involvement you may have had in the events that took place at full-time on May 21, 2016. In the meantime your membership has been placed 'on hold'."

A spokesman for the club refused to confirm how many letters had been sent out, describing them as "private communication" to individual supporters.

A total of 38 people have so far been arrested in connection with the pitch invasion, which saw mounted officers called in to restore order.

The SFA described the conduct of some fans as "contemptible behaviour".

Police inquiries are ongoing and an independent commission report, requested by the SFA, is expected to be published later this week.
