Dutch military police say the five men and two women were tracked down based on new information
Seven people have been detained over a multimillion-euro diamond heist that occurred nearly 12 years ago.
The Amsterdam diamond heist was one of the biggest diamond robberies ever recorded.
On February 25th 2005, armed robbers hijacked an armoured car at a secure area of Amsterdam's Schiphol Airport and made off with diamonds worth more than €67m.
Many of the stolen stones were uncut and as such were difficult to put a definitive value on - with some commentators putting the value of the haul closer to €110.
In a statement, Dutch military police said they have arrested five men and two women in Amsterdam and Valencia over the past two days on suspicion of involvement in the armed robbery and money laundering.
The Royal Marechaussee police said part of the stolen haul was recovered soon after the robbery - however diamonds worth approximately €40m remain missing.
Police said the seven suspects, all Dutch nationals, were tracked down based on an investigation of new information.
