Officials at FairPoint Communications say two acts of vandalism to its network on New Year’s Day affected about 1,000 customers.

Spokeswoman Angelynne Beaudry said in a statement that the vandalism occurred in Harrington, Maine, and Amherst, New Hampshire.

Dispatchers with the Washington County Sheriff’s Office and the State Police, which share coverage responsibilities for Harrington, said they had no record of vandalism being reported in the town on Jan. 1. Calls to FairPoint seeking more details about the incident were not returned Friday night.

Beaudry’s statement said that in both cases the damage was done by those who know telecommunications equipment and how to damage the network.

Company officials renewed their offer Friday of a $5,000 reward for information leading to the arrest and conviction of the vandals.

“This infrastructure is essential to safety services and to the customers who rely on it, and we will not tolerate sabotage of valuable company assets that provide such critical services to the public,” she said.

Union officials have said the company is struggling to maintain its systems and accused FairPoint of making “bogus insinuations.”

More than 1,800 FairPoint Communications workers in Maine, New Hampshire and Vermont went on strike Oct. 17.
