Translation guide
In Japanese, referring to an 'assailant' depends heavily on context, such as the nature of the attack, legal vs. news reporting, and whether the attacker is known or unknown. The most common and neutral term is 犯人 (criminal/culprit), but more specific words exist for different situations.
To refer to a person who physically attacks someone, often in a crime context. This is the most common and versatile term.

There is no single Japanese word that perfectly matches 'assailant' in all contexts. Using 襲撃者 for every case can sound unnatural. Choose based on the specific situation: crime (犯人), fight (攻撃者), sexual assault (痴漢 or 性的暴行の加害者), etc.
犯人 (criminal) implies guilt has been established, while 容疑者 (suspect) is used before conviction. In news, 容疑者 is often used for an arrested person, but 犯人 may be used for a fugitive. Be careful with legal nuances.
The suspect denies the charges.
