The scale of the insider trading scandal in Brau Union shares has increased, according to local reports. Weekly publication News said yesterday (2 November) that the number of people implicated has risen to 30 from the initial 23. News cited information from the Austrian financial market authority (FMA) in its report.

Among those suspected in trading in the Austrian brewer prior to its takeover by Heineken in 2003 are members of the former owners' families and company staff. They are alleged to have earned around EUR9.38m (US$11.3m) from the takeover.

The suspects allegedly used confidential information relating to Heineken's acquisition to speculate with Brau Union shares, which were listed on the stock exchange at the time, the report added.
