A 36-year-old police inspector has been placed under close arrest over the alleged assault of his 14-year-old son.

Police are investigating the matter as assault causing actual bodily harm. Preliminary investigations showed the inspector allegedly threw a hammer at the teenager earlier this month, striking his left ankle, after the boy reportedly misplaced a key.

Further enquiries disclosed that about 7:30am on Wednesday, the inspector allegedly became angry after the teenager failed to complete his household chores. He reportedly locked the boy in a bedroom and beat him about the body with an electrical extension cord, injuring him.

The matter was reported to the Childcare and Protection Agency, which launched an investigation. The teenager was interviewed by the relevant authorities and taken to the Leonora Cottage Hospital, where a doctor examined him.

Police ranks later visited the location. The inspector was placed under close arrest on Wednesday, pending investigations, which are ongoing.
