Missing suitcase - No 30 bus - Dublin Airport to Cavan on 13/04/13

I got on the bus at Dublin Airport on Saturday 13/04/13 at approximately 2pm. I placed my small black suitcase (cabin baggage) into the hold before getting on the bus. The first stop was Virginia (approx 3pm) where some passengers got off, the next stop was Cavan (approx 3.30pm) where I was getting off, only to realise that my suitcase was gone from the hold. At first I thought that someone had taken it by mistake but I took the driver's phone number and phoned him later in the evening and he said there was nothing left on the bus when all the passengers had got off in Donegal. I have been in contact with the Gardai at the Airport, Virginia and Cavan, but nothing has been found yet. I suspect that it was stolen somewhere along the way. If anyone has any information please contact me, Thank you. Paula @ 0876450803
