As an almost NPPL(M) licence holder who also owns a drone, I really do hope the investigators / police recover the bits of the unit involved in the strike.
It'll likely have a memory card with recorded footage, and maybe even a GPS log so they'll have more clues as to who was operating the thing at the time.
The person responsible really needs to be caught and made an example of. A crippling fine & a custodial sentence might just dissuade other
from similar idiocy.
Other drone hobbyists are equally outraged.
