Be careful when flying domestic from Denpasar airport.
I flew this morning with Garuda from Denpasar to Surabaya, and some tools were stolen from my check-in luggage.
I know that there was a problem with stolen items from checked in luggage some month ago, and I think the police made some arrests, but apparently the problem still exists.
Don't put anything valuable in your check-in luggage, or at least lock your bag or suitcase (I didn't).
