The theft of eight and a half tons of Titane 30, from one of the warehouses of the company Titanite SA, in Plévin on September 28, 1999 by an ETA and ARB commando is one of the most spectacular achievements of the ARB to date (the security alarm system had been carefully dismantled). This incident served to confirm suspicions about the nature of the relationship between the ETA and the Breton separatists. As the subsequent investigation revealed, ARB members had been hosting Basque separatists in Brittany prior to the heist. Spanish authorities even suspect that some ETA members may at times come to Brittany temporarily in search of a safe haven.
