What type of information indicates that the accused has previously committed a similar offence?

The chosen answer, similar fact, is correct because it specifically refers to evidence that demonstrates the accused has engaged in previous conduct that is analogous to the current allegations. This type of information is crucial in legal contexts, as it can establish a pattern of behavior that may support the argument that the accused is likely to have committed the offense in question. Courts often assess similar fact evidence to determine its relevance and credibility in establishing guilt or intent, particularly in criminal cases.

Corroborating evidence, while it serves to reinforce the credibility of primary evidence, does not necessarily indicate prior offenses. Character evidence relates to the overall disposition or traits of the accused rather than specific past infractions. A background check provides a general overview of an individual's history but may not directly link to particular similar offenses being considered in the current case. Thus, similar fact is more precise and directly relevant for establishing that the accused has a history of similar wrongdoing.
