The biggest ETA arms cache found by Spanish police has now grown substantially from the original 850 kilos of explosives which were discovered in a country house in Legorreta, Guipúzcoa, on Tuesday.

There were new searches at the site on Thursday, leading to the discovery of hundreds of kilos of explosives in an outbuilding near the house where the first cache was found. El Mundo reports that the amount is so large, that an exact figure cannot be given at this stage.

RTVE Spanish National Television said the total amount now, including Tuesday’s find, could be as much as two tons.

A previously undiscovered pistol was also found in a second search of the country house.

José Aitor Esnaola, one of the two brothers who were arrested in Legorreta early on Tuesday as part of ETA’s logistics operation, and who lived on the property, was with the Civil Guard officers who carried out the search.

The search, which involved 300 Civil Guard, police officers and the Tedax bomb disposal squad, then moved up into the mountains at the border with Navarra, where another ETA hideout was found to contain an unspecified amount of cash and a weapon.

José Aitor Esnaola and his brother Igor formed part of ETA’s Erreka commando, and were responsible for supplying other ETA cells with weapons and explosives.

Público reports that the Civil Guard arrested another suspect on Thursday, as yet un-named, who is accused of collaborating with Erreka.
