LG Offices Raided Over Alleged Samsung Washing Machine Vandalism

South Korean prosecutors raided the Seoul headquarters of LG Electronics on Friday following allegations that the firm's executives vandalised their rival Samsung's washing machines at a trade fair in Germany, company officials said.

Samsung Electronics had filed a lawsuit accusing the LG executives of defamation, property damage and obstruction of business and said LG home appliance division president Jo Seong-Jin was among those who damaged machines displayed at September's event in Berlin.

Investigators seized documents and computer hard disks during Friday's raid on LG headquarters, Yonhap news agency said, adding that the company's home appliance factory in the southern city of Changwon was also searched.

"Our office is under scrutiny by investigators," an LG spokesman told AFP, declining to give details.

Samsung said surveillance video footage from the fair showed several men -- which they later identified as LG executives - destroying door hinges on the washing machines.

Samsung has also accused LG of making slanderous claims that its washing machines were defective.

LG rejected the accusations in a statement, saying the company is "concerned that its business activities and brand image will be severely damaged because of the competitor's unilateral and unreasonable opinion".

Samsung produces a range of electronic products and leads the global markets for mobile phones and flat-screen TVs.

Its smaller rival LG is one of the world's biggest manufacturers of home appliances including refrigerators and washing machines.

The two have for years locked horns in the home market over a series of bitter PR disputes regarding the supremacy of their products and technology patent lawsuits.
