HONG KONG police detained an English baronet after he was allegedly caught in possession of cannabis. Sir Hugo Cunliffe-Owen, 28, was arrested with two friends outside his Parkview Court home in Lyttelton Road, Mid-Levels, last Monday. Officers found what is believed to be 25 grams of cannabis in his pocket. The substance has been sent to the government laboratory for further analysis. A baronet is the lowest hereditary order of British nobility. Sir Hugo, 28, who told police he did not work but later admitted being employed ''in the financial sector'', refused to comment on his arrest when contacted by the Sunday Morning Post. The baronet was only 17 when he succeeded to the title on the death of his father, Sir Dudley, in 1983. The family's fortunes were established from a gambling casino and the prestigious Palace Hotel on the Isle of Man. Also arrested with Sir Hugo were a Briton and an American. Police also claimed to have found what appeared to be a gram of cocaine. The three share the same flat. They have been granted bail and will return to Central Police on September 25.
