The Metropolitan Police have promised "targeted and new appeals" for information about Madeleine McCann's disappearance as detailed phone records are helping them build up a picture of who was in the area at the time.
Earlier this week, Scotland Yard revealed that:
- 41 people of interest have been identified
- These include 15 UK nationals
- 31 international letters of request have been sent, mostly European countries
- A large list of phone numbers belonging to people in the area has been drawn up
