Police are continuing to investigate a serious assault at Wynnum on Sunday morning.
Officers were called to a Bridge Street sports ground around 11.30am where a group were engaged in a physical altercation.
Investigations suggest the initial assault was unprovoked and took place when a 35-year-old man was pushed down a set of stairs, knocking over a 59-year-old woman.
The man attempted to remove himself from the confrontation by walking on to the sports ground, however the altercation continued and more people became involved.
Detective Inspector Stephen Hollands from the Bayside Patrol Group said the extensive investigations are ongoing.
“We are working through a large amount of statements and footage to determine the circumstances of the assault,” he said.
