Towards the end of their ride, a security guard spotted the four skaters and told them to leave.
"And we told him that we were leaving anyway, but then he just started sprinting at us and we just started running," Joel, 17, told the Herald.
"Then he caught up to my friend [Jerome] and took his board."
Jerome then started filming on a camera he had brought with him so the skaters could film their tricks.
Joel said the group knew they were in the wrong and wouldn't go back to Eden Park, but called the guard's actions "pretty uncalled for".
Eden Park spokeswoman Tracy Morgan would only say that there was a break-in at the park on Saturday and that the people were caught and evicted.
The guard could not be reached for comment.
