Hi,
The answer is - It was found near a ditch near my house.

Hi,
The answer is - It was found in a ditch near my house.
We do not write 'by me' as in most cases we do consider to write this detail.
And as the form of the passive:
object + verb + doer
The sentece obtained is- It was found in a ditch near my house.

Hope it is helpful.
