A Mexican donkey has been freed from jail after doing time for assault and battery. The Televisa network on Wednesday showed "Blacky" gobbling food from a bucket after spending three days in a jail that normally holds people for public drunkenness and other disturbances.Blacky was jailed for biting and kicking two men near a ranch outside Tuxtla Gutierrez, the capital of Chiapas state. Officials freed the donkey after its owner paid a fine of $36 and the $115 hospital bill of the men, who suffered bites to the chest and a broken ankle. Authorities say he also must pay $480 to each man for missed work days.
