POLICE continue to investigate a huge fire which swept through part of an industrial estate, destroying several lorry trailers.

Huge plumes of smoke were seen over Cwmbran when the fire happened at the Avondale Industrial Estate.

Firefighters battled to extinguish the flames, which engulfed several detached trailers on the afternoon of Saturday, June 4.

At the time, South Wales Fire and Rescue Service said it believed the incident should be treated as a crime scene.

And now, three months on, Gwent Police confirmed the force was conducting an arson investigation after the fire was "deemed to be deliberately started".

One Cwmbran resident told the Argus he heard "at least four or five loud bangs" coming from the scene.

He described seeing "a plume of smoke billowing up into the air" and said "there's clearly been some sort of huge explosion".
