The 24-year-old claims he was attacked by up to five staff at a fairground ride on land at Boucher Road on Monday evening during family day out.
He claims he was assaulted after he complained that one of the ride’s was unsafe when the bar opened while his wife and daughter were onboard and had to cling on for their lives.
His epileptic daughter later suffered a seizure fit as a result of her scare.
During the fracas, his toddler son’s pram was pushed upside down and he smashed his eye off the ground.
The child sustained a bump to his head and cut underneath his eye and around his nose.
The father sustained fractured ribs, bumps to his head, cuts to his face and neck, and a dislocated shoulder.
He and his son were taken by paramedics to the RVH hospital for treatment.
The police are investigating the assault.
PSNI Inspector Murphy said: “Shortly before 6.50pm, it was reported that a 24-year-old man was assaulted in the area.
“He was taken to a nearby hospital for treatment to injuries that are not believed to be life-threatening.
“Inquiries are continuing and police are appealing to anyone who was in the Boucher Road playing fields area between 6pm and 6.50pm and who may have witnessed the incident to contact police at Musgrave Police Station on the non-emergency number 101.”
A Planet Fun spokeswoman said: “We can confirm that an incident took place on Monday night.
“This is now a police matter and it would be inappropriate to comment further.”
