Police are investigating the armed robbery of a servo in Brisbane's South West early this morning.
It's believed at around 2.30 a.m., two men forced their way into the Sumners Road business at Riverhills by smashing the glass doors.
They then jumped the counter, threatened the staff member with a hammer and a machete and struck him in the head with the hammer.
The duo then snatched the till containing cash and fled the scene in a stolen white Mazda 3...driven by a third man.
The staff member sustained minor injuries.
