PSNI played 'catch-up' after late report of Arlene Arkinson disappearance

Detectives in the North investigating the disappearances of missing schoolgirl Arlene Arkinson were at a disadvantage because of the delay in reporting her missing, an inquest has heard.

Brian Lavery, a former Police Service of Northern Ireland (PSNI) detective sergeant who reviewed the investigation papers for the National Crime Faculty, said there is only a small window of opportunity to gather evidence in such cases.
