Gardai in Waterford City are investigating two incidents in which property was damaged by fire overnight.
A petrol bomb was thrown at a house in Dominic's Place while a car was set on fire in Grantstown Park.
The house in Dominic's Place was attacked at 3.45am with the owners believing it was a case of mistaken identity.
Gardai are carrying out house to house enquiries and checking on CCTV in the area.
The damage was caused to the exterior of the property including the front door and guttering.
The occupant of the house, Pat O'Brien, told Damien Tiernan on Deise Today that three petrol bombs were thrown at the front of the house.
He says the person or persons who threw the petrol bombs escaped on a motorbike.
"Whoever did this was out to do real damage.
"If it had gone through the window, Alan was in the room there.
"We think it was a motorbike, someone on a motorbike.
"It was attempted murder."
Garda forensic teams are examining the scene at the moment.
A car was damaged by fire in an earlier incident at Grantstown Park.
It happened at Sylvan Drive at 12.15am.
Witnesses reported hearing a motorbike rev its engine outside the house around the time of the incident before taking off.
