Arson fear for town.
Limavady, Co Derry, has been hit by no fewer than 20 fire attacks so far this year.
A weekend blaze at a country park in the town has also given rise to concern that serial arsonists are on the loose.
A local councillor said: "I am very concerned and frightened at this latest attack.
"The perpetrators are vandals and when caught they shouldn't just get a slap on the wrist but feel the full force of the law."
