Bala still alive

Bala still alive. He rang up his nephew and telling him he is safe but can't tell where the place he is hiding now. In the phone Bala's wife told him they call from a phone from a policeman which with private number.
Why last few days police told media they don't know where's Bala, but now from what Bala's wife told is they borrow a phone from a policeman to call back.
Who can we believe to?
