Executives from Argentine supermarket chain Disco, which is owned by Dutch retailer Ahold, have been subpoenaed by an Argentine judge as part of a massive tax evasion case involving around 180 companies.

The directors are like to appear in court this week after a massive investigation by national tax agency Afip into some 180 companies for the alleged use of false invoices, Dow Jones News reported, citing sources. No one has yet been charged in the case.

The source also said Disco could have been on the receiving end of fake invoices and would, in that case, be innocent of tax evasion.
