Why would someone dump another rabbit in my garden ?

Last month someone dumped a very small very young baby rabbit in my garden , It was alive but very skinny and too young to be away from the mother . I kept it and its doing very well now its grown in size and has put on alot of weight . But last night someone dumped a pure breed Lion Head rabbit in my garden , Must have be about 6 -8 weeks old is very healthy looking and plump .
Why me no1 here knows I used to breed rabbits and other animals , no1 in this area even knows who I really am ( my choice I stay away from everyone )
What would make someone buy or even steal a rabbit to only dump it . I say steal cause I don’t have a clue where any came from .
I get my treatment free from the vet cause the first rabbit was dumped , I was a good client of his anyway with my past animals i.e owls, rabbits, snakes ,lizards, hamsters etc…. but there’s no way they will believe me another rabbit was dumped .
Edit : Both rabbits were in cardboard boxes and the time spaced between one rabbit and another would be three weeks .
