Matutes has now decided to donate €100,000 to the National Police Orphan Foundation in thanks for their work, Spanish newspaper El Mundo reported on Monday.
One of the suspects in the crime — a decorated officer — was a well-known rally driver who had just announced plans to open a driving school on the island.
Police believe other people were involved in the robbery, although the two officers taken into custody were key to the plot.
The holding company Matutes owns businesses including an international hotel chain, several construction companies and real estate firms.
In 2012, it notched up earnings up €300 million.
