Rehearsals of La traviata, which were to start this week at the Gaiety Theatre in Dublin, have been delayed.

David Collopy, the company's CEO, said, "I am sure U.K. customs and excise along with the Gardai [Irish police force] and Belgian police can source where the drugs came from and release the shipment of costumes so there are no further delays to us going ahead with our winter production."

To Reuters, Collopy said, "This is not our doing, believe me. We don't know how the drugs got in there."
