Those behind a series of arson attacks targeting 5G mobile phone masts in west Belfast have been urged to “wise up”.
Four masts were damaged in arson attacks carried out in just over 24 hours.
The fires are believed to have been started deliberately.
Fires were reported at two masts in the Upper Springfield Road area shortly before 1am on Tuesday.
Firefighters attended and both were extinguished within an hour.
Another report of fire at a mast at Stewartstown Road was later received at around 10pm on Tuesday, and dealt with.
A short time later, just before 1am on Wednesday, another report was received, this time in the Monagh Bypass area, with a fire crew dispatched to extinguish it.
A spokesperson for the NI Fire and Rescue Service said the cause of all four is believed to have been “deliberate ignition”.
A PSNI spokesperson said a link between the four incidents is being investigated.
The latest incidents follow an arson attack on another 5G mast in west Belfast’s Distillery Street area last month.
The Springfield Road, Monagh Bypass and Stewartstown Road areas were also the scene of a series of arson attacks on 5G masts in June last year.
Speaking after this week’s attacks, west Belfast SDLP councillor Paul Doherty said: “Those behind these arson attacks need to wise up and stop causing destruction and disruption in their own communities. Engaging in this kind of activity is absolutely futile.
“Whatever the motivation behind these incidents, our police and fire service have much more important things to be dedicating their resources to than this. It must stop now.”
He added: “Anyone with any information about these attacks should come forward to police as soon as possible.”
