Around £1,000 worth of damage was caused in an attack on equipment used to connect homes in rural villages to superfast broadband.
The community initiative, Fibre for Rural Nottinghamshire (F4RN) in Fiskerton cum Morton was launched when residents were told they would be left out of a county scheme.
So far, 110 properties have been connected, with more on a waiting list.
Work was continuing over the weekend on Station Road, Fiskerton.
Having finished at 5pm on Saturday, the team resumed on Sunday morning, only to discover ducting that was ready to connect homes to the fibre broadband had been cut. Two drums of ducting, close to the works but in separate locations, had also been cut.
Ducting is used to carry the fibre, which improves connectivity for residents.
It is believed secateurs or pruning shears were used to inflict the damage.
“I cannot find ways to describe it, or to think what the reason was,” said Mr Chris Horne, one of the directors of the project.
“If it was mindless vandalism then I could understand it, but someone has taken the time to work their way up the road, cutting every one of the ducts.
“They have then gone to two separate drums, in two separate locations, sawing through every layer.
“But this is not going to stop us, we are going to press on.
“It has slowed us down a bit, but we will complete the project.”
'It's hard work but worth it'
Mr Horne added that the attack was particularly galling given that the scheme is being carried out by volunteers.
“The work is being done by members of the community who are giving their time. It’s hard work but worth it,” he said.
“So this is really an attack on them. People were coming up to us on Sunday, not believing that this had happened.
“Every surplus we generate, we put back into the project.
“Currently there is a real push to get Fiskerton finished and, despite this attack, we want to do it by the end of the year.
“The speeds that people are getting are fantastic, so we want to continue.”
The long-term aim of the project is to connect 370 homes in the two villages.
