Using this information, find out who the thief is?

Question

Three people met at a corner of a street. They all are dressed like cops, so they don't know who's the thief (bad guy). The cops will tell the truth (because they are good), and the thief will tell the truth too to make himself appear like a good cop. They are A, B and C. And they say this:

A:"C's not the thief."
B:"One of you both is the thief!"
C:"I'm not the thief."

Using this information, find out who the thief is?

Answer 1

As per the condition all three of them will tell truth:
according to a c is not thief ,A and B remains
B says one of you are thief: that means A and C, but as c can't be thief because if he being thief is a contradiction
hence A is thief.

Answer 2

a is the thief.. because , let b &c are cops so they are right,
b says- thief is between a & c,
and c says- i m not the thief,
so a is thief.

Answer 3

A is the thief.
B says the truth, because he is not the thief. Cops always say the truth
C says the truth. I am not the thief. Again Cops always say the truth.
Therefore, A is simply guesssing that C is not the thief
