A woman from Nevada was arrested at South Station for allegedly beating her “tiny Yorkshire” in the bathroom at the busy transportation Hub.

According to MBTA Transit Police, around 7:45 a.m. on November 15, a concerned passenger approached officers and alerted them that Ana Prado, 26, was “badly abusing a small dog” inside the lavatory.

The witness told police that Prado, who is from Henderson, Nevada, was hanging the dog in the air by its leash and allegedly kicking and punching the pup.

A female Transit Police officer entered the women’s restroom and escorted Prado outside where she was placed under arrest for cruelty to animals, the report said.

The dog was turned over to the City of Boston’s Animal Control Division and was evaluated by a veterinarian for any injuries.

According to police, Prado was in Boston to attend Suffolk Superior Court for a charge of drug trafficking.

Jake Wark, a spokesman from the Suffolk DA’s Office, said Prada was scheduled to be arraigned Thursday in Suffolk Superior Court on the drug trafficking charge but was instead arrested for allegedly “beating her tiny Yorkshire Terrier in the ladies’ room of South Station.”

Prado was indicted on October 15 after she allegedly forgot two rubber gloves full of painkillers at the Logan Airport Hyatt Hotel a month prior.

The animal abuse prosecution is something that MSPCA Law Enforcement Officer Christine Allenberg says the state takes very seriously.

“Anytime someone intentionally harms an animal, if we have enough evidence to put a case together, yes, if it is an act of cruelty we will prosecute,” said Allenberg.

Allenberg is currently dealing with a case in Southbridge, Massachusetts, where a man allegedly trapped a skunk for days in a yard over the summer and let it die slowly.

“Dying through heat exposure —it’s slow and painful for these animals, not to mention the emotional distress the animal went through. It was trapped for at least five days in the heat,” she said.

The suspect, Lionel James Gaumond, was charged with one count of animal cruelty, a felony.

He appeared in Dudley District Court on Thursday during a pre-trial conference, according to Allenberg.

“This skunk died in an excruciatingly painful way over the course of several days—a period in which he had no access to food, water or shelter from the heat.  I’m pleased that we are on the way to securing justice for this animal,” she said.

Allenberg said animal cruelty is something she deals with daily, and in cases where peoples’ pets are involved, it is usually because of a lack of shelters or places for owners to get rid of the animals.
