NECN – (NECN) - Massachusetts authorities are on the lookout for the thieves responsible for a horse hair heist.

Ringo Tarr of Gloucester says his pet miniature horses have been robbed of their tails.

It's the second time it's happened.

"About a year ago, it was about the end of September, I was putting the horses in one day and I happened to notice their tails were all cut. All of a sudden this year the same thing happened," said Tarr.

"There's a big market for jewelry, horse hair jewelry," he added.
