A man has been shot by police after he allegedly slashed an officer across the face with a knife soon after police arrived at his Brisbane residence on Wednesday afternoon.
The alleged offender was rushed to hospital in a critical condition, while the injured officer was taken to hospital with serious, but non life-threatening, injuries.

Paramedics were called about 5pm and took both patients to hospital.
