An eyewitness report is a report that is written from the first-person point of view. This allows the writer to provide an account of the events that occurred from his/her perspective. It, therefore, means that the writer of this type of report is a witness to the events being reported.
An eyewitness report is often taken in the case of a crime or accident. It must be noted that like all expository writing when writing an eyewitness report you should only share the facts, not your opinion.
