A teenage boy was taken to hospital after allegedly being attacked by a group of youths in Cardiff's Llandaff Fields on Sunday evening.
The 14-year-old boy was left shaken and covered in bruises and swollen after being attacked before a member of the public intervened.
It's understood the group set upon the boy twice and had gone in for a third time when they were called out by some passing adults, who then called the police.
Witnesses described being "intimidated" after observing a group of boys running over with balaclavas. They said: "Not the lovely walk in Pontcanna that it should have been; [it] should be a safe place for all."
