'Absolutely devastated'
One of those whose vehicles was torched was Joni Whitfield, whose car was parked in Tudor Way when it was set alight.
"I was absolutely devastated about the car," she told the Observer.
"My partner Phil works in Pembroke Dock, so for us a car is essential.
"The car was completely burnt out, but nothing was stolen. It just seems that this was mindless vandalism."
Joni continued: "I cannot believe that someone could be doing this to us and to the other people involved the week before Christmas.
"For Phil and I, having to bear the cost of replacing the car and the hassle of dealing with insurance at his time, is very difficult. I just hope whoever is responsible is found before someone gets hurt."
