As many as 600 homes in Bishopbriggs are currently unable to use their telephones after cables were stolen.
It’s understood copper cables were taken from manholes in Westerhill Road, between Hillside Drive and Loggan Road, in the early hours of Thursday morning, around 2am.
Residents have been left unable to use their phones or access the internet.
BT workers are at the site and it’s been reported that it could be Sunday before the phone lines are restored.
Dominic Notarangelo, chairman of Bishopbriggs Community Council, is among those affected. He said: “I discovered the lines were down when I went on-line from the laptop about 6am.
“This is having a big impact on the area. There are a lot of elderly people in Bishopbriggs who could be left in vulnerable situations.
“People have been going to the library to use computers to get online.”
Police said they have arrested a 36-year-old man for the theft of BT cable in the Bishopbriggs area.
Chief Inspector Rob Hay, area commander for East Dunbartonshire said: “This sort of crime can cause significant disruption to the local community including loss of power and telephony which affects the vulnerable members of the community who reply on these services.
“It can also be extremely dangerous for those who perpetrate this type of crime. Any information on similar crimes or any other type of crime please contact Police Scotland on 101 or Crimestoppers on 0800 555 111.”
