The Herald Sun is reporting that a man allegedly left a bomb in a Melbourne pub.

The incident occurred this morning after a 45-year-old Derrimut man left what looked like a bomb at the WestWaters Hotel & Entertainment Complex after a dispute with staff.

He was arrested soon after.

“It’s alleged he left an item resembling an old army ordnance device at the premises before leaving,” a Victoria Police spokeswoman said.

Police are conducting safety checks and the man is assisting police.
