A man has been detained by police over threats to British celebrity chefs Jamie Oliver and RICK STEIN. The threats were sent by email to the two TV cooks by a group calling itself the Cornish National Liberation Army (CNLA). The organisation vowed to destroy and damage property. A spokesperson for Devon and Cornwall police says a 36-year-old man from the port of Padstow, where Stein runs his Seafood Restaurant and other businesses, has been arrested in connection with the incident. In an email attributed to the CNLA, Oliver was targetted because he was "another incomer who has caused the inflation of house and other living costs at Cornish expense". The suspect has been released on police bail until 14 August (07) when he must appear at Newquay police station. The CNLA, which claims to have "substantial" funding from America, wants Cornwall to be granted independence from Britain based on historic evidence that it is not a county but a separate province.
