TERRIFYING footage has surfaced of an out-of-control house party - which forced a mother to hide her newborn baby from violent revellers.

The teen host's father was also knocked unconscious and left with a broken jaw in the Saturday night festivities in Perth, according to local media reports.

CCTV shows a mob of more than 60 young men and women fighting and a fence post and a brick being thrown though a rear glass door - which police say narrowly missed a newborn baby inside.

"Several calls were made to police after uninvited guests began smashing bottles in the backyard of a house, and began spilling out onto the street shortly before midnight," a WA Police spokesman told news.com.au.

"A brick was thrown through the window of a house narrowly missing a young baby and a man who confronted the brick thrower was knocked unconscious," he said.

The father was taken by ambulance to Rockingham Hospital and is in a stable condition.

It is believed the event in Waikiki was a farewell party for a 17-year-old because the family is moving to Victoria.

According to local media reports, neighbours who tried to help calm the situation said they had bottles thrown at them, were struck with bricks and, in one instance, wounded with what may have been a shiv.

ABC reports neighbours retreated into a backyard before several youths armed with various bats, sticks and metal bars jumped the fence.

9 NEWS claims to have a recording in which the homeowner and mother of the teen hosting the party can be heard yelling at her daughter.

"Well go to the f***ing cops ... your father's f***ed up, the house is f***ed up ... they're your f***ing friends," she is reported to have said in the recording.

The mother, identified only as Rebecca, told 9 NEWS she was shaken by what had happened.

"But I got three kids and you know it's just, yeah, hopefully it doesn't happen again," she told reporters.

Police say investigations into the violence are ongoing and no arrests have been made. Anyone who can assist with identifying suspects is asked to call 131 444.
