Key dates in the disappearance of Madeleine McCann
LONDON (Reuters) -Three-year-old Madeleine McCann, from Rothley, Leicestershire in central England, disappeared on May 3, 2007 during a holiday with her parents in the Algarve region of southern Portugal.
Sixteen years on, Portuguese police on Tuesday started searching a reservoir inland from where she disappeared.
Here is a chronology of developments.
2007
May 3 - Madeleine goes missing from her bedroom between 9.30 p.m. and 10 p.m. while her parents Kate and Gerry are dining with friends just 100 yards away at a resort in Praia da Luz. A window and shutter are open and she is presumed to have been abducted.
May 4 - McCann family members and British media criticise local police for what they call a slow initial response, failure to notify ports and borders in time, and failure to secure the crime scene.
May 5 - Police say they have put together a sketch of a suspect and confirm they believe Madeleine is still alive and being held within three miles of the crime scene.
May 8 - Police say they have investigated 350 suspicious incidents but still have no idea where she might be.
May 10 - The search around the resort winds down.
May 11 - Former England soccer captain David Beckham makes a televised appeal for information.
May 13 - Billionaire Richard Branson, author J.K. Rowling and footballer Wayne Rooney are among those to have contributed to rewards totalling 2.5 million pounds.
May 14 - Police search a villa just up the road from where Madeleine was snatched and take a British man, Robert Murat, to a police station for questioning. He is later released.
June - The McCanns travel to Spain, Germany, the Netherlands and Morocco to appeal to the public to help search for their daughter.
September - Kate and Gerry McCann are questioned by Portuguese police. They are both named as suspects, but police do not bring charges against them. The couple then fly back to Britain with their twins Sean and Amelie. In a brief statement after landing, Gerry says: "We have played no part in the disappearance of our lovely daughter Madeleine."

March - McCanns accept 550,000 pounds of libel damages from the Daily Express and Daily Star papers over allegations it made that they were involved in her death.
