Authorities have dropped charges against a New York City teenager accused of killing her younger brother's hamster.

The Brooklyn district attorney's office on Friday cited "inconsistent statements from the witnesses" in dropping the charges.

The 19-year-old was accused of choking and squeezing the 4-ounce hamster named Sweetie in June, before throwing it to the floor. It was later tossed across the street. The teen was arrested Tuesday night.

She told the New York Daily New that she did not kill the hamster.

The case was investigated by the American Society for the Prevention of Cruelty to Animals.

The ASPCA said in a statement Friday that it stood by its investigation. The organization said it was saddened that there would be no prosecution in the animal's death.
