Inspector Harmer said early investigations suggested some form of conflict occurred nearby moments before Mr Roberts entered the restaurant, but there were no obvious signs of injury.

“We believe there’s been some sort of conflict earlier but we’re not aware of any injuries of those involved parties and all those involved parties have provided versions to police and have assisted us with our inquiries,” he said.

The Toowoomba CBD’s City Safe CCTV network captured the incident, with police receiving live alerts as it unfolded.

“We are very fortunate in the Toowoomba CBD to have the City Safe program that is monitored by police, that enables us to have rapid response,” Inspector Harmer said.
