The detective is back

The Mona Lisa is again missing and services of Byomkesh are required again. Here are some observations that he has made:

At least two people were involved in the robbery and the robbers left in a truck.

Only four people - Azeem, Bartok, Charlie, Drones (and nobody else) can be involved in the robbery.

Charlie cannot do the job without getting some help from either Azeem or Drones. 

Azeem and Drones are mortal enemies and would kill each other. They only listen to Charlie and only Charlie can stop them.

Neither Bartok nor Drones can drive.

Bartok never does a job without Drones.

Byomkesh decides to make his first arrest in the case. Can you say who gets arrested?

Ans: Charlie
