A former Brisbane employee of a Wacol business has finally been arrested after an hour-long siege inside a frozen food plant.

The man was armed with a “large knife” and has not left the factory since 10 pm on Wednesday. However, police officers reported that the man was threatening the workers in the plant. This led to the evacuation of the Vesco plant located in Wacol on Grindle Road.

The officers entered the plant after 8 am on Thursday, where they arrested the 46-year-old without causing him any injury.  Police added that the man cooperated with them later and followed their instructions, which made it a peaceful mission. The investigations were still ongoing, the officers confirmed.

“In the early hours of this morning [Thursday], specialist police entered the building at Vesco and a male person who is 46 [was] taken into custody peacefully,” a police spokeswoman told reporters. “He complied with police direction and has been taken to the watch house for investigations. No words were spoken when he was taken into custody.”

The police described the man as a “disgruntled” ex-employee of the plant.

As soon as the siege was reported, paramedics, specialist officers and a dog squad reached the spot and surrounded the plant. Police declared an emergency an hour before they planned to storm the building under the Public Safety Preservation Act while the negotiators had a conversation with the Brisbane employee via the PA system.

It was reported that the man climbed on the building’s ceiling through the night but the officers compelled him to come down early Thursday.

Inspector Sean Cryer stated that as the Brisbane employee did not respond to the negotiations made from outside the plant, the officers had to storm the building. “He has entered the building armed with a knife, so we do believe he is still armed with a knife and we do believe he’s still inside the building,” The Daily Mail quoted Cryer as saying on Thursday prior to storming the building. “We’re trying to negotiate and get him to surrender and come out.”
