The state government is facing calls to remove children from police adult watchouses after it was revealed they are being held there for weeks at a time.

Premier Anastasia Palaszczuk and state government ministers were asked yesterday to explain how a girl was held in the same area as two alleged male sex offenders in the Brisbane City watch house.

Doctors and the Queensland Law Society have called for the age of criminal responsibility to be raised from age 10 to 14.
