A suspicious fire broke out at the LUX Nightclub on Chapel Street in Melbourne early Thursday morning, prompting a response from around 50 firefighters. The fire, which started around 1:45 AM, took nearly two hours to bring under control, and fortunately, no one was inside at the time. Chapel Street has been closed to traffic due to structural concerns, and a health warning for smoke has been issued for local residents. Police have established a crime scene and are investigating potential links to recent fires, with reports of suspicious figures seen fleeing the scene. As of now, no injuries have been reported, but the investigation continues with a police arson chemist expected to arrive on-site.
