How do you handle a 9 yr old firebug?

Question

My 9 yr old son will not stop playing with matches,lighter etc.. We have caught him trying to light a fire under his sisters bed (with her in the bed) Our neighbors have caught him out back with a lighter and papers with leaves & sticks trying to make a fire. He steals the lighters he has because we dont use them in our house.

We have shown him pics of burn victims and he smiled. We took him to the local fire station and they spoke to him but it hasn't worked.

his graet grandma took him to the burn unit at the hospital she works at but according to her he seemed not to care,like he was bored.

I need help bad. Any ideas other than set him on fire I will think about.

Also I have no clue what catagory this should be in.
