Ant and Bell are two siblings who live together. Ant is 20-years-old and Bell is 12-years-old. Cat and Dan are two of their neighbours.

One day, a friend of Ant's brings a couple of small boxes containing small plastic sachets with white powder and asks Ant to hide them somewhere safe until she comes to collect them. Ant accepts the request but finds the secrecy odd. He opens one of the sachets and realises that these are drugs. Concerned, he hides them in the cellar.

Cat suspects something 'fishy' and knowing that Ant has had problems with the police before, threatens him that if he does not steal Dan's $500 bike, she will tell the police that he is involved in illegal activities. As Ant says nothing, she adds that she will also run Bell over with her car when Bell returns from school, and make it look like an accident.

Ant is terrified of the threats. Ant also remembers that he once took Dan out and paid $100 for his drinks, but Dan never reciprocated. Ant takes Dan's bike (which was chained to a tree on the kerbside outside Dan's property) and moves it less than a metre away, across the fence, onto Cat's property.

Dan confronts Ant about the stealing of the bike. Bell observes the heated discussion between Ant and Dan. Bell takes a stick from the ground and hits Dan, causing several bruises on his leg.

Annoyed, Dan goes to the police and complains that Ant and Bell are involved in unlawful activities. Upon a lawful search of Ant and Bell's residence, the police discover a quantity of 50 grams of white powder. Lab tests conclude that the white powder was amphetamine.

With reference to relevant authorities, consider the following:

A.1. Ant's liability in relation to the taking of Dan's bike and any relevant defence/s.[15 marks]

A.2. Ant's liability for drug-related offences.[10 marks]

A.3. Bell's likely charge for the injuries caused to Dan, and Bell's liability in the light of his age.[5 marks] [NB: In relation to the charge, you should not analyse in detail the elements of the offence committed by Bell. Simply indicate what the charge is likely to be, explain why, and provide the relevant authority.]
