Despite the viral Snapchat video of the culprits who attempted to catch Whanganui's Riding for Disabled (RDA) horses, no prosecution has been brought.
In November last year two horses were injured by a group of people who got into RDA's paddock and tried to catch the animals.
The video, which was plastered over social media, showed a snippet of the incident with one horse trying to flee as a man held on to its tail.
RDA chairman Ray Stevens said Facebook users provided names for some of the people in the video, which were passed on to police.
"All we know is that they are under 20 years old and known to the police," he said.
