Ipswich detectives have charged four teenagers following the serious assault of a man at Redbank Plains earlier this month.
At 8.30pm on Tuesday, September 8, the 21-year-old was confronted by a group at a shopping centre along Redbank Plains Road.
It will be alleged the man was assaulted with baseball bats, before the juveniles fled in two vehicles, a Mazda 323 and Mitsubishi Lancer.
The man was taken to Princess Alexandra Hospital with serious but non-life-threatening injuries.
Three 17-year-old boys from the Ipswich area have been charged with one count each of acts intended to cause grievous bodily harm and affray.
A 16-year-old Yeronga boy has been charged with acts intended to cause grievous bodily harm, affray and contravening an order.
Anyone with further information is urged to contact police.
Investigations are continuing.
