Attention:
The Public Prosecutor, Plovdiv Region
Dear Sir,
I am outraged by the barbaric treatment of a dog captured on a photo which was published on Facebook on 7th Jun, 2013.
I understand that the animal was subjected to this heinous torture very recently and that it happened somewhere in the Plovdiv Region, Bulgaria.
I respectfully ask you to investigate the crime, find and punish the perpetrator who tied the dog and dragged it behind a car with registration number РВ 5730 АР, as shown on the photo.
Yours sincerely,
Name
Country
