Melbourne authorities are investigating a firebombing at a cafe that occurs just days after the business was attacked with bullets. Multiple reports say the cafe is targeted again after the earlier incident in which shots were fired and the premises were sprayed with bullet impacts. In the newer attack, a firebomb is used, causing damage to the cafe and prompting an emergency response. Police are treating the incidents as linked due to the short time between attacks and the fact that the same venue is targeted. The reporting indicates the cafe has been left unsafe and requires assessment for damage and repairs. Investigators are working to determine who is responsible and whether the attacks are connected to broader criminal activity or a dispute. Sources note that questions remain about motive, the identities of suspects, and the extent of injuries, if any. Police urge anyone with information to come forward as investigations continue and evidence is collected from the scene of both incidents.
