"They are not suggesting he stole Maddie but he may know people who could have been involved after a burglary went wrong".
Three-year-old Madeleine McCann disappeared from a ground-floor apartment at Portugal's Algarve resort in Praia da Luz, a resort town often nicknamed "little Britain" due to the high concentration of English tourists who holiday there.
The Mirror reported that police are searching for a Portuguese man who worked at the Portuguese resort, the Ocean Club, during the disappearance.
In a move that has been described as the "last roll of the dice" to get to the bottom of what happened to little Madeleine McCann nearly a decade ago, British authorities have granted investigators an additional £85 000 (about R1,1 million) to continue the probe until September. Authorities say he "kept secrets" from them during the initial investigation. The McCanns had lived in Rothley, Leicestershire during the incident. "There are no immediate plans to reduce office numbers further at this time", a spokesperson said of demands to call it quits in the search for Maddie.
A series of suspects have been questioned, but there have been no solid clues.
A family spokesman said: "Kate and Gerry remain incredibly grateful to the Home Office and the Met Police for the continued work into the search for their daughter".
Her parents Kate and Gerry McCann have campaigned tirelessly since then to try and find out what happened, and have vowed never to give up hope that she may still be alive.
An extra 85,000 pound ($103,000) has been allotted to extend the missing girl's search for six more months between April and September, the British Interior Ministry said on Sunday.
Her parents had left Madeleine and her younger twin siblings asleep while they went for dinner with friends at a nearby tapas restaurant.
