The arrests were made on Monday, the investigations being into alleged criminal organization, disclosure of secrets and coercion. It is understood that the arrested officers are stationed in Calvia, Marratxí and Palma. Some are said to have worked at Palma Son Sant Joan Airport and at the Marivent Palace, the Royal Family's residence in Palma.
In addition, it would appear that three other people have also been arrested. One is believed to be a member of the military and the others from a security company.
The case, it is being reported, centres on the commissioning of officers to follow a man's partner and to inform him of all her movements while she was in Mallorca.
Officers from the Guardia Civil's Central Unit for Internal Affairs came to Mallorca from Madrid over the weekend and made the arrests.
