Police are seeking voluntary interviews with those who attended the funeral of veteran republican Bobby Storey in Belfast in June.

Detectives are investigating potential breaches of Northern Ireland’s coronavirus regulations on gatherings.

Mourners on June 30 included senior Sinn Fein representatives like Deputy First Minister Michelle O’Neill and Finance Minister Conor Murphy.

Deputy Chief Constable Mark Webster of Cumbria Constabulary was appointed to oversee and direct the Police Service of Northern Ireland (PSNI) inquiry.

He said: “Today an initial number of letters were issued to individuals who were identified as having been present on 30th June in potential breach of the health protection regulations.

“The letters are inviting these individuals to participate in a voluntary interview with investigating officers at a local police station.

“Upon receipt of a letter, individuals will have 14 days to respond should they wish to take part in an interview.”

Ms O’Neill and Mr Murphy have denied breaching social distancing measures while at the funeral.

Hundreds of people lined the streets in west Belfast as Mr Storey’s funeral cortege passed by despite the restrictions and despite marshals being present.

A row with the DUP over the matter prompted the suspension of joint briefings with Sinn Fein during the health emergency.

A Sinn Fein spokesperson said: “A number of the party’s elected representatives have received letters from the police this morning asking them to present for voluntary interview.

“They will contact the police and co-operate with the investigation.”

DUP MLA Mervyn Storey welcomed the move.

“The focus on process is one thing and I’m glad to hear progress but an outcome is the most important,” he said.

“It is 81 days since the Covid-19 rules were fundamentally undermined by that event.

“This case, like every other investigation, must be based on the principle that everyone is equal under the law and be equally subject to the law. No-one is above the law.”
