Should the complainant have witness in case of a common assault and how many should one have?

In a common assault case, having witnesses can significantly bolster the complainant's credibility and support their account of events. While there is no strict requirement for a specific number of witnesses, having at least one or two credible witnesses can provide corroborating evidence that strengthens the case. Ultimately, the more reliable witnesses available, the better the chances of substantiating the complaint.
