An appeal has been launched after a number of items were taken from Finn Park over the weekend.
The incident happened on Friday night following Harps defeat to Bray Wanderers.
A Rode microphone and accompanying cable were taken from the grounds.
The club says that footage of the incident has been captured on CCTV.
A spokesperson also afforded the opportunity to those involved to return the microphone and cable to the clubhouse over the coming days or further action will be taken.
