The RNC says its investigation into a suspicious fire at the FFAW building on Hamilton Avenue earlier this month remains active.
Investigators are awaiting lab results related to exhibits collected from the crime scene.
The FFAW called the incident a “serious attack” against the union.
The Constabulary is asking the public for any CCTV or dash cam footage from the area around 4:30 on the morning of Sunday, April 4.
