A man wanted over a horrific attack that left his girlfriend with head-to-toe injuries has been arrested after a dramatic pursuit in which an elderly woman was carjacked and four vehicles were wrecked in Brisbane.

The man faces a string of charges, including torturing and attempting to disfigure his 21-year-old girlfriend, who was found with shocking injuries at a Bulimba unit nine days ago.

She was found after a panicked man made an anonymous call to police. She's still fighting for her life in hospital, suffering burns and what police called "significant injuries to the front of her entire body, significant injuries from head to toe".

Officers hunting for her 31-year-old partner went to a Stafford property late on Monday but he allegedly jumped in his car and took off, ramming two police cars as he fled.

He then abandoned his damaged vehicle and pulled an elderly woman from behind the wheel of her car and took off in that, police say.

The police helicopter tracked the stolen car to Nundah, where it was also abandoned, and the man allegedly stole yet another car before crashing that into the gate of a property.

He then fled on foot and forced his way inside a Clayfield home, where officers arrested him.

The Bald Hills man has been charged with acts intended to disfigure, acts intended to cause grievous bodily harm, torture, deprivation of liberty and supplying a dangerous drug.

He will face Brisbane Magistrates Court on Tuesday and police expect to lay further charges against him over Monday's pursuit.
