Dozens of protesters chanting "free the dogs, arrest the criminals!" say that about 50 stray dogs seized in connection with five deaths in a Mexico City park in recent weeks are innocent and should be released.

The city prosecutor's office says initial tests on the first 25 strays indicate there is no evidence they ate human flesh. However, officials are still awaiting results from tests on their fur to see if any human DNA was present on the dogs.

Since mid-December, the bodies of three women, a teenage boy and a baby have been found in a hilltop park with dog bites.

Protester Nominis de Esparza said Friday that protesters are convinced that humans killed the victims, not dogs. They say the dogs may have bitten the bodies after death.
