An EFL spokesman said:

“The EFL has today been made aware of the contents of correspondence published by the Grimsby Town Mariners’ Trust and a media statement released by officials at Stevenage FC in relation to events that are alleged to have taken place at Saturday’s League Two game between Stevenage and Grimsby Town.

“At this current time the EFL’s Security Advisor is looking further into the matters raised and will be seeking the observations of both Clubs. We are not in a position to make any further comment until such a time when all the facts have been made available and are fully considered.”
