LONDON (Reuters) - Portuguese police were searching a reservoir on Tuesday about 50 km (31 miles) from where British three-year-old Madeleine McCann disappeared in 2007, authorities said.

The move was the most recent development in the search for McCann whose disappearance 16 years ago triggered a global hunt and huge media attention.
