UPDATE 11AM: AT LEAST one of the people allegedly sitting inside a car containing a suspicious device is known to police. 

The suspicious device was contained in a cardboard box  in the passenger footwell.

Queensland Police Senior Sergeant Gareth James said Safe City cameras noticed the car's position and suspicious activity by its two occupants. 

A man and woman, one who is known to police, sitting in the silver Nissan hatch were arrested and taken to the Ipswich watchhouse. 

Senior Sergeant James said their motives "at this stage were totally unknown and subsequent to further investigations". 

A 100m exclusion zone remains in place while the contents of the box are being investigated. 

"The bomb squad are examining it, there is a possibility the device could actually be blown by the bomb squad," Senior Sgt James said.
