Sinn Féin MLA John O'Dowd has said the actions of the Orange Order in Portadown yesterday were a clear breach of a Parades Commissions determination.
The Commission had ruled that no parade or gathering was permitted at the controversial arch at Victoria Terrace at the bottom of the Garvaghy Road.
John O' Dowd said:
"The Orange Order’s actions yesterday were in clear contradiction of their own call for legal protest.
“It is illegal to breach a Parades Commission determination and their actions could have led to a breach of the peace.
“There are also questions for the PSNI who when contacted by SF claimed that local people were mistaken and that the Orange didn't gather at the arch.
“ We have since supplied the PSNI with the photograph and a statement which appears to be from the Arch committee.
“I will be seeking a full explanation from police as to why they claimed to unaware of this illegal assembly.
“If I am not satisfied with their response I will hand the matter over to the Police Ombudsman.”
