(Corrects headline and story to make clear Vekselberg and two investors paid 10 mln francs to end investigation)
* Vekselberg owns controlling stakes in Oerlikon, Sulzer
* Already cleared of fine for Oerlikon stake
ZURICH, Oct 18 (Reuters) - Russian billionaire Viktor Vekselberg, who holds controlling stakes in Swiss industrial groups Oerlikon and Sulzer, and two other investors have paid 10 million Swiss francs ($10.4 million) to end an investigation by Swiss authorities.
Swiss authorities had been looking into whether Vekselberg and investors Ronny Pecik and Georg Stumpf violated disclosure rules when they built up a stake in Sulzer but closed their investigation after the three investors paid compensation, the Swiss finance ministry said on Monday.
Last month, a Swiss court cleared Vekselberg of violating disclosure rules when he built up his stake in Oerlikon. Vekselberg was facing what would have been a record fine of 40 million francs in that case.
