Investigators conducted four searches in the Ljubljana and Celje areas. Tuš Holding told RTV Slovenia that investigators did pay them a visit but denied that the searches were related to current business operations. However, RTV Slovenia has learned that the searches were related to an embezzlement case that involved the sale and transfer of the now defunct Tušmobil brand. The mobile carrier brand was sold but discontinued in 2014, and Tuš had already made a similar move when he sold the rights to the Engrotuš brand, said Tomaž Modic, a Siol journalist who covered the case.

The investigation was reportedly prompted by complaints from three creditor banks, NLB, SID banka, and Gorenjska banka. Moreover, the banks filed a criminal complaint against Tuš. Tuš is also expected to be sued over the controversial granting of 3G licences in 2008.
