UPDATE 2PM: a 29-year-old man is assisting with police investigations following an alleged attempted car jacking at Yamanto this morning.
Police arrested a man in dramatic circumstances after he forced two women from a vehicle at traffic lights on Warwick Rd about 9am.
Earlier in the day, the suspect had been spotted several times on rural properties south of Ipswich, prompting calls to police from residents.
Police said they made several attempts to intercept the utility, stolen from Greenslopes on Thursday, without success.
Police were informed about 8.30am that the vehicle was at a quarry at Purga, with workers having blocked the ute in with their machinery.
The man then allegedly fled the scene on foot and stole another vehicle from a property nearby, crashing through a fence as he sped off.
Police followed this stolen vehicle to Warwick Road in Yamanto where it was abandoned.
The man then allegedly forced the driver and a passenger of a passing car out of their vehicle and police then arrived on scene as the man locked himself in the car.
Police were forced to smash the window and the man was then taken into custody.
The man was taken to hospital for observation in relation to a medical condition and no one else was physically injured as a result of the incidents.
A 29-year-old man is currently assisting police with their enquiries and investigations are ongoing.
