NEW YORK (TheStreet) -- Shares of Gerdau SA (GGB) - Get Gerdau S.A. Sponsored ADR Pfd Report stock are down 1.16% to $1.70 late Tuesday afternoon after Brazil's police accused the country's largest steelmaker and its CEO of corruption-related offenses, the Wall Street Journal reported.

Filed Friday in federal court, police are seeking charges against Chief Executive André Gerdau Johannpeter and 18 other company executives, tax authority officials and lawyers for evading 1.5 billion reais or $428.6 million in taxes owed by the firm. They are being sought on charges of bribery, money laundering and influence peddling, a police spokesman told the Journal yesterday.

Last night, Gerdau wrote in an email to the Wall Street Journal that the firm has not yet seen the report containing the accusations but assured its executives never "promised, offered or gave improper benefits to public functionaries so that cases open in CARF would be illegally judged in their favor."

The charges against Gerdau come as part of the Brazilian police's Operation Zealots investigation. The probe was launched in March 2015 and has led police to pursue allegations that Gerdau executives bribed tax officials to win favorable judgments from a special tax court known as CARF, the Journal said.

In February, the firm's offices were raided and Johannpeter was questioned by police for two hours, according to the Wall Street Journal.

Gerdau's shares have dropped as much as 6.7% after the corruption allegations leaked. The average volume for the Rio De Janeiro-based company has been 11.58 million shares per day while this afternoon Gerdau had 17.30 million shares on heavy trading. Gerdau has a market cap of $3.4 billion and is part of the basic materials sector, and metals and mining industry.
