Two people have been arrested by the Intelligence and Investigation Service of the Dutch Food and Consumer Product Safety Authority in connection with a Dutch horse meat scandal, the Dutch public prosecutor announced on Thursday.

Willy Selten, the owner of meat wholesaler Willy Selten BV, was detained Thursday on suspicion of fraud and forgery for alleged involvement in false labeling of meat products, two days after deputy director was taken in police custody.

Prosecutor said the company had processed 300 tonnes of horsemeat from suppliers in the Netherlands, Ireland and Britain between 2011 and 2012.

Since the horsemeat scandal erupted in January, governments have scrambled to figure out how and where the mislabeling of meat happened. Brussels has suggested tighter controls along the food chain as well as stiffer sanctions against food fraud.
