Cash-strapped Eric Tang Yiu-hong and Eugene Tang Yiu-chuen have been struck a further financial blow in the form of a lawsuit seeking $7.9 million from the former German Kitchen directors. They are being sued by Jetluxe Investment for the alleged unpaid debt as well as interest and costs. The brothers acknowledged the debt in July last year, but 'despite repeated requests', have failed to pay the amount due, a High Court writ says. The brothers were also recently the target of legal action launched on behalf of German Kitchen (China), claiming they hold the sum of $137.4 million as constructive trustees on behalf of the firm. The brothers are also fighting bankruptcy petitions filed against them.
