Business owner Peter Nguyen shared his loss on social media and started a GoFundMe to support recovery efforts, highlighting the community's support for those impacted.

The incident resulted in the collapse of the roof and ongoing smoldering inside the building, complicating efforts for firefighters to conduct a thorough investigation.

The fire's aftermath has led to ongoing safety concerns, with emergency crews continuing to monitor the site and manage smoke affecting nearby communities.

Fortunately, no injuries were reported, as fire and emergency services responded promptly around 12:40 a.m.

An emergency meeting with affected business owners is scheduled for Wednesday morning at Morley Public Library to discuss the incident and next steps.

Over 130 emergency responders, including police, paramedics, and 25 fire trucks, responded to the scene, where the fire destroyed a 5,000 square meter building, prompting road closures and emergency alerts.

Authorities are seeking public assistance, including CCTV and dash-cam footage, and have urged anyone with information to contact Crime Stoppers as the investigation into the arson continues.

A deliberately set fire overnight at Morley Markets in Perth's north caused extensive destruction, including the collapse of the roof and damage to dozens of small businesses, notably the 20-year-old Bishop St Newsagency.

The fire, which broke out around 1 a.m., was contained by firefighters to the original structure, preventing it from spreading to nearby buildings, but the building was deemed too unsafe for detailed investigation.

Residents in the area, including parts of the City of Bayswater and City of Stirling, were advised to stay indoors with windows and doors closed due to smoke and ongoing emergency management.

The fire was confirmed to be deliberately set, with the Arson Squad investigating; a suspect linked to WA's tobacco wars was recently banned from the markets during a bail amendment.

Several roads, including Bishop Street and Progress Street, remain closed, and motorists are advised to avoid the area as authorities manage the scene.
