I have been observing this issue. In one point may be Ajay had done something he should not be doing but in the other hand as new things are coming up made me think twice. Now I am thinking something is not right in this case.

Hypothetically: I am not trying to degrade any body. As students from high school steps in college some of them may not able to cope the freedom. Similarly girls may be overwhelm by the freedom and she may had accompanied with wrong people which may have fueled Ajay and was unable to stop her and he may be the victim?   Or after knowing all this he may has some involvement too?  Once she was in Nepal, Ajay did not wanted to bring her back may took it in different level and my be some conspiracy from either side?
 
Any body in her place will be extremely mad and frustrated. . She may have in the same anger during the conversation which has been taped. Those word may mean it or just an expression of frustration but it is the one took  toll on Ajay.

Justice must prevail.
