The first time someone allegedly snuck onto Brent Tarr’s Gloucester farm and snipped hair from his miniature horses was last year.

Then it happened again in September. The animals at the family farm were targeted for a third time in the past few weeks.

Tarr, 64, wants it to stop. This week, he decided to speak out about the hairy crime, to make sure that other farmers are aware of the trend and that it doesn’t continue.

“I didn’t expect them to come back a second time. And definitely didn’t expect it a third time,’’ said Tarr, who added that everyone knows him by the name “Ringo.’’

“I’m just hoping for one thing: they stop doing it,’’ he added. “And that we catch them and see what their motive was.’’

The strange crime, which involves someone apparently using shears to haphazardly cut away the thick hair from the manes and tails of Tarr’s miniature horses, may sound random. But similar incidents have been reported across the country, with some police officials conjecturing that the hair is used to make fancy jewelry or as extensions for show horses.

Tarr’s four miniature horses range in age from 6 to 26. Only three were targeted. He keeps them on a five-acre farm on Essex Avenue, in Gloucester. The small horses are family pets, he said, and share space with goats.

Tarr at first thought it was a Halloween prank or maybe the hair was being used for a costume. But when it occurred twice more, he was slightly befuddled.

“I got to thinking maybe it’s for jewelry, or for some kind of profit. I just don’t know,’’ he said. “It’s very common out West.’’

According to WNWO-TV, a Toledo, Ohio, station, thieves recently used scissors to remove hair from the tails of two horses at a farm in Ida, Mich. The station reported similar horse-related offenses have happened in Wyoming, Colorado, Illinois, and Missouri.

After the most recent incident in Gloucester, Tarr said, he called the police. He plans to install cameras in the area in an attempt to catch the perpetrator.

Tarr said the animals don’t appear to have been injured, but by removing the hair it puts the animals at a disadvantage. Horses typically use their tails as fly swatters, swishing them back and forth to scare away pesky bugs.

“They have no way to shoo them off and get them off of them, so they just land on them and bite away at them,’’ he said.

Plus, the jagged new haircuts are highly noticeable.

“Normally, the tails almost touch the ground,’’ he said. They don’t now, he said, adding “their hair doesn’t grow back fast.’’
