The suspect, Kumpa Somsri, was arrested at his rented apartment for allegedly fatally hitting the dog in the head with a hoe while it was feeding five puppies on Tuesday night.
He then reportedly grilled the dog despite passers-by urging him to stop. Kumpa also sustained facial bruises during a scuffle with angry neighbours who tried to take away the dog carcass.
He is facing charges of theft and animal cruelty but he maintained his innocence.
