Yu Shangqing, a policeman receiving treatment in the capital for serious injuries he suffered in an explosion, is in grave danger, Beijing News reported on Thursday. A doctor said the officer, from Harbin, Heilongjiang province, is being kept alive by a ventilator, blood pump and other equipment. More than 100 pieces of shrapnel remain in Yu's body following the explosion in 2003. He was defusing bombs that had been left at a hotel in Harbin when one exploded, leaving him blind in one eye, deaf in his right ear and with a badly injured leg. He was transferred to Beijing in August after falling into a coma.
