Police are searching for a group of people following a series of incidents on Grey Street at South Brisbane last night.

At 9:15pm a group of people entered a business and attempted to steal alcohol before being challenged by an employee.

A scuffle ensured and the employee was hit on the head with an unknown object, causing minor injuries.

The people fled with some of the alcohol in a stolen blue 2008 BMW sedan with registration JSM62.

About an hour later the same people re-entered the business and attempted to steal alcohol before being challenged by an employee.

They left empty handed and are described as Aboriginal or Torres Strait Islander.
