What happened to the pistol?

The story of Australians being held for attempting to carry a disassembled pistol and bullets onto a plane in Syria has been downgraded to ‘young boy souveniring a used cartridge’.
The son of one of four Australian women detained in Syria amid fears of a hijacking plot says an empty gun cartridge souvenired by a child travelling with them sparked the drama.
But the lead in the original article was based on the disassemble pistol.
Early reports about the women’s detention had said a dismantled gun was found inside a toy carried by a child who was with them.
So what happened to it?
