The Northern Territory's Chief Minister Adam Giles has promised to stop his government counter-suing two boys who are seeking damages for being tear-gassed at a notorious youth detention centre two years ago.

The former inmates of Don Dale Youth Detention Centre near Darwin, are being sued for damages totalling $160,000 following a ram raid on the jail after the boys had escaped in a stolen car.

They rammed a jail garage door when they returned from their escapade.

Disturbing footage of the tear gassing incident at Don Dale Youth Detention Centre near Darwin, as well as vision of a 17-year-old boy being handcuffed, hooded and strapped to a mechanical chair, was aired by the ABC's Four Corners program on Monday.
