Bike getting lost

University of Madras, chepauk. The bike parked in the parking lot of the university with watchman guarding the premesis is getting lost. and things stolen from bike.
Incident 1:
My bike’s horn and cut out were stolen 7 months ago in university of madras chepauk’s parking lot.
incident 2:
An activa of my classmate, (a Chinese guy) lost it in the same parking lot(no insurance).
incident 3:
Another friend of mine lost his splendor bike before 3 months parked opposite to the university. That was actually in the Marina beach.(splendor, blue-black,no insurance)
incident 4:
A guy lost his splendor parked in the University bike parking a week ago (no insurance).
All the bike stealing incidents seen here were planned on uninsured vehicles. This makes me suspicious that whether the insurance companies do this or some one related to them do this.
Or else it could be this, some guy brilliantly tracing out bikes that are not insured. Because if those bikes were insured then the company that does insurance may pressure police to find the bike. This might be the cause i guess. Till today there is no solution.
