Gardai from Wicklow town have renewed their appeal for information following a series of deliberate fires on the site of the old Veha radiator factory site at the Murrough.
Fire-Service units from Wicklow Town and Rathdrum arrived at the scene on Thursday evening around 6pm and spent over two-hours getting the blaze under control.
Polystyrene, reels of old cables and other materials had been piled-up in the middle of one of the warehouses and set alight.
Gardaí have started increasing patrols in and around the Veha site in an effort to cut down on any anti-social behaviour taking place in the area.
Sergeant John Fitzpatrick says their investigations are ongoing.
