Section 122

A person attending court who is not under arrest or has not been served with a summons may be detained by the court for examination for any offence which the court may deal with, and which from the evidence the person appears to have committed.

The court may proceed against the person as though the person had been arrested or summoned.

When the court proceeds against a person under this section during the course of a trial, it must begin the proceeding against the person separately.
