A building belonging to the Quinn Group in Co Fermanagh has been damaged in a fire tonight.

Police said they are treating the blaze at the premises in Derrylin as suspicious.

The fire comes weeks after a lorry was driven in to the canteen of another Quinn building.

A spokesman said the blaze was reported shortly before 7.00pm, by which time the fire had already caused damage to the building.

Detectives in Enniskillen have appealed for anyone with information to come forward.

Former billionaire Sean Quinn has condemned the attacks and called for an end to the incidents.
