The chairman of the Policing Board has written to the chief constable over concerns raised by prominent loyalist Jamie Bryson linked to a PSNI operation in east Belfast earlier this year.
The move comes after Mr Bryson contacted Doug Garrett to voice concerns over a PSNI operation linked to a gathering in east Belfast in February.
At the time police faced criticism for not intervening after a large group of masked men marched through the Pitt Park Park area.
Police later said the incident was linked to the UVF.
Mr Bryson says that to date 22 people have been arrested in a follow-up operation and that police have used the Terrorism Act.
Three men are facing charges arising from the incident.
In his letter to Mr Bryson, Mr Garrett confirms he has been in contact with Simon Byrne.
"You have requested that the Policing Board raise the issues with the chief constable and I can advise you that I have written to him to seek his response to the various matters of concern that you have raised," he wrote.
Mr Garrett added that he also provided the correspondence from Mr Bryson to the board earlier this month and discussed it with the oversight body's human rights advisor.
"The board will consider the issues further pending receipt of the chief constable’s response and I will revert to you on receipt of this," Mr Garrett added.
Mr Bryson last night said there are "significant concerns as to the deployment of Terrorism Act legislation in the Pitt Park case, which ultimately relates to a non-violent public order incident at its very height".
He said his letter to the Policing Board was on behalf of 28 individuals and seven community groups adding "it is welcome that answers are now being sought from the Chief Constable by the policing board".
