Police feared others were carrying knives after park users reported seeing men "flashing" their weapons.

One man, aged in his early 20s, was shot by police with an electric stun gun after he set his pitbull-type dog on an officer.

He and eight others were arrested for offences including attacking police, public disorder, affray and handling stolen goods.

Three children, aged between five and 12, who were riding past the brawl, were thrown when their horses became frightened. They suffered broken bones.

Paramedics took all three to hospital for injuries including suspected broken bones and concussion.
