lets go with what we know. As of Nov 2016 the satellite is offline according to the Euros and a parliament query several months later mentions it is missing.. So let's cut to the chase. China took it out. With a missile. Thus is an extreme interpretation of "fragmentation event". They have the capability and possible as a warning to the surgical strike. Seems a bit heavy handed and very swift. Then ISRO does damage control saying the satellite has difficulties but is still present when it isn't etc etc. It's advised not to point a phone camera at a laser show as even a second or two direct exposure can damage the camera sensor. Here we are dealing with an item that is several hundred km's above earth and moving at several times faster than a speeding bullet. I think it would be very difficult to use a ground based laser to disable a satellite. The inverse square law makes it very difficult. Chinese don't have any known space weapons. Until such time i will go with the simplest explanation. How about a mechanical fault. That isn't unheard of. https://www.deccanherald.com/national/iaf-five-crashes-last-21-days-719350.html We lost a mirage in Banglore just few weeks before Balakote where it worked perfectly and all 6 returned safely. Mig 21's crash from time to time, known as flying coffins yet one went into a dog fight and took out a F16. They're calling it a world's first.
