Police are questioning a man over a series of arson attacks on 5G masts in Belfast.
The 45-year-old was detained following a planned search of a property in the west of the city yesterday.
He remains in custody on suspicion of 26 counts of arson.
"We are very aware of the damaging impact these incidents are having on the community," said Detective Inspector McAnee.
"The disruption to network signal is affecting many people's day-to-day lives, particularly those who are more vulnerable and rely on these services for their healthcare, work and connection with others.
"This remains an active investigation with multiple lines of enquiry being pursued. We are committed to catching those responsible and stopping these attacks," he added.
He is the second person arrested in relation to arson attacks on 5G masts in Belfast.
Last week a 44-year-old man appeared in court charged in connection with an arson attack on a mast.
He was remanded in custody.
Police told the court that damage costing £4m had been caused to masts in west Belfast since 2023.
