Joshua Taylor, 19, of Junortoun, and his co-accused Jordan Baker, 19, of Kangaroo Flat, appeared in the Bendigo Magistrates Court charged with armed robbery.

The court heard the men forced entry into the home of Owen Napier, who was sentenced to a 12-month community corrections order last week, with the intent of "knocking him out" of the drug market.

Taylor pointed the shot gun at Napier's chest while Baker searched the unit for drugs and money.

Police informant Detective Senior Constable Glen Fisher told the court the pair stole $600 and five grams of cannabis while chastising Napier about "dealing weed" and warning him not to contact police.

A week later, police caught up with Taylor by chance, in relation to a traffic matter, and found a shot gun hidden underneath the back passenger seat of his car.

He denied committing the armed robbery.

Meanwhile, Baker assaulted a police witness and sold cannabis and exchanged it for methamphetamine.

Detective Senior Constable Fisher said Baker's mobile phone was intercepted and "it's a case of actively trafficking the drugs and also having it in his possession and offering it for sale".

Baker was arrested on April 24 and denied committing the armed robbery and assaulting the police witnesses.

"He did admit to offering nine grams of cannabis for sale, which he said he couldn't sell and used himself," Detective Senior Constable Fisher said.

Baker initially made an application for bail which was dropped after information his defence was not aware of came to light.

Detective Senior Constable Fisher told the court Baker was addicted to methamphetamine and cannabis and even supplied cannabis to his father.

Detective Senior Constable Fisher said there was also evidence Baker's father had knowledge of the armed robbery.

Baker and Taylor were remanded in custody to appear in the Bendigo Magistrates Court on July 9 for a committal mention.
