The violent group can be heard shouting “run that shit … get it, get it, get his wallet … I got his phone” as someone can be heard pleading, “stop, stop … please mate, please”.
Tony, who asked his surname not be published, said his 16-year-old son had his phone stolen in the chaos.
“There were about 200 kids down at the beach and then 10 or so of these other kids came down and they just started throwing fists and kicking and stealing anything possible that they could get away with,” he said.
“One of the kids came up to my son with an empty wine bottle and waved it over his head and said, ‘Give me your phone and unlock it, give me the passcode or you know what’s going to happen’.
“A girl was bashed, a couple kids had their heads stomped on, there were multiple kicks. One of the girls had their shirt ripped off … it was adult-style bashing; just appalling stuff you’d go to jail for, not just a slap on the wrist.”
Police, in a statement to Radio 6PR, said detectives were investigating several incidents in the City Beach and Floreat areas overnight.
“There were multiple reports of robberies and at least one teenage boy was taken to the Perth Children’s Hospital for treatment of facial injuries,” the statement read.
“The investigation is in its early stages but detectives are urging anyone in the City Beach/Floreat beach area last night that has phone or dash-cam vision of any incidents to please contact Crime Stoppers on 1800 333 000 or report online at www.crimestoppers.com.au.”
