What term describes unwanted and repeated attention by a suspect towards a victim?

The term that most accurately describes unwanted and repeated attention by a suspect towards a victim is stalking. Stalking involves following, monitoring, or pursuing an individual in a manner that causes fear or distress. This behavior is typically persistent and unwanted, going beyond mere harassment by creating an ongoing pattern of behavior that can have a significant psychological impact on the victim.

In contrast, harassment generally implies unwanted behavior or communication but does not always carry the connotation of a systematic approach that stalking does. Intimidation refers to instilling fear through threats or actions, which may not involve the repeated attention aspect. Assault involves physical actions intended to cause harm or the threat of harm, which also differs from the repeated attention characteristic of stalking. Thus, stalking is the most appropriate term for the described behavior.
