The Pretoria Magistrates Court has denied suspended police officer Fannie Nkosi bail on Wednesday.
The court ruled that Nkosi failed to prove that his release is in the interest of justice.
Nkosi brought the application after his arrest earlier in April during a raid at his home.
He faces firearm-related charges after seven guns were found at his home. He has also been charged with possessing dockets that were allegedly found in his wendy house.
Nkosi will be remanded in custody until his next court appearance in May.
