Four teenagers have now been charged over a home invasion that saw Wallabies great Toutai Kefu hospitalised with critical wounds to his abdomen.

The 47-year-old, his wife and two of his adult children were admitted to hospital after Mr Kefu disturbed the alleged burglary in their suburban Brisbane home on Monday.

The four alleged offenders, aged between 13 and 15, have been charged with a combined total of 44 offences including attempted murder and grievous bodily harm.

One was arrested at the scene on Monday and two others were charged in the days following the incident.

Further charges were laid on Thursday against a 15-year-old boy who was admitted to hospital after the alleged burglary and later discharged.

All four were denied police bail and were due to appear before the Brisbane Children’s Court.

Mr Kefu has been released from hospital.
