Hells Angels saw their "death head" logo on a Mambo sweatshirt, they reached not for the baseball bats of stereotypical bikie lore, but for their lawyers, in a bid to protect their intellectual property. The Australian has revealed that Gazal Corp - Mambo's previous owner - has been forced to apologise to the motorcycle club, following a hard-fought legal stoush which began in the federal Magistrates Court late last year. As part of a confidential settlement in favour of the bikies, Michael Gazal, managing director of Gazal Corp Ltd, penned an apology to the Hells Angels Motorcycle Corp (Australia) Pty Ltd, for manufacturing and selling the garments. "Gazal would like to publicly acknowledge the Hells Angels' intellectual property rights in its trademarks and artistic works, and the considerable reputation it has in those trademarks and artistic works, a reputation which stems from a long history of use both in Australia and internationally," the apology, obtained by The Australian, reads. The offending garments were a child's hooded sweatshirt and a sugar-pink mini-skirt.
