The President was arrested and charged with several crimes, including animal abuse, document forgery, fraud, practicing a profession without qualifications and illegal appropriation.
Another two employees at the shelter were arrested and a fourth person is charged in the case.
Animals were allegedly sacrificed “on mass, in a deliberated, continuous and unjustified manner” with no veterinary control and using very low doses of the euthanasia drug to save money, causing the animals to suffer a slow and agonizing death.
The detainees were set free with charges but the mayor ordered that the centre be closed for six months and fined €15,000.
The judge has ruled that the closure cannot be based simply on a complaint and that a verdict must be reached first.
