The three deliberate fires were in underground cable chambers in the Springboig area between midnight on Thursday and 8am on Saturday.

Police Scotland said none of the fires were at 5G sites – but they did cause "severe disruption" to hundreds of businesses and homes.

A fibre chamber in Threestone Hill and a copper cabling chamber at the junction of Croftspar Drive and Springboig Avenue were set alight between midnight on Thursday and 1am on Friday.

Police are investigating a series of fires.

There was another fire at the Croftspar Drive site between 2am on Friday and 8am on Saturday.

Police Scotland believe the incidents are linked.

Detective Sergeant Lisa MacDonald said: "We believe these three incidents are linked. Neither of these chambers are 5G sites.

"Not only is fire-raising dangerous, this has caused severe disruption to several hundred businesses and home customers, who during these challenging times will be relying on virtual technology and the phone to keep in contact with customers, family and friends."

In the last few weeks, conspiracy theories falsely claiming the deployment of 5G networks has caused – or helped the spread of – Covid-19 have been linked to a surge in attacks on 5G masts.
