Authorities in Great Britain want to talk to more than three dozen people after they renewed an investigation into the disappearance of Madeline McCann, CNN says.

The young girl was 3 years old when she disappeared in 2007 while her family vacationed in Praia de Luz, a town on the Algarve coast in Portugal.

According to CNN, Metropolitan Police in London want to talk to 38 persons of interest who may be connected to Madeline's disappearance. A dozen of them are British citizens who were in Portugal at the time.

Police say they still have reason to believe Madeline is alive.
