Hong Kong ( CNN ) -- A 13-year-old boy is in intensive care in Beijing after two adults assaulted him by releasing compressed air into his body using a mechanical pump at an automobile repair shop . Chinese media reported that the boy , Du Chuanwang , who lives in Shandong Province on China 's east coast , suffered from dozens of puncture wounds in his intestines and multiple organ failure . The boy helped out at the auto repair shop , where two co-workers allegedly inserted the nozzle of an air pump into his anus and filled his body with air . The suspects have been detained . Local police posted a message last week on Sina Weibo , China 's microblogging site , saying that the two men pushed the boy to the ground during the attack , and that the incident was a `` prank . '' Ai Qingze , the head of the Shandong hospital where Du received initial treatment , told the China Daily newspaper that upon seeing his inflated belly , the surgeons there cut his abdomen open to expel the gas and saw that his small intestines were bleeding . Ai said the boy 's liver , kidneys and stomach were also damaged . Family members of forced abortion victim in China cite continued harassment . Du was in a coma for eight days following the assault . He woke up three days ago and was transferred to the intensive care unit at Bayi Children 's Hospital in Beijing on Thursday . `` We can only provide the necessary life support to him for now , as his condition is very complicated , and the doctors have not yet devised a final treatment plan , '' a hospital official told CNN . Hospital officials declined to give more details about Du 's current condition . Angel Mom , a charity group that helped arrange the hospital transfer , posted on Weibo that Du has a serious nose infection that is causing necrosis . A photo in the post shows massive decay of the boy 's nose and cheek . The post also said that after 20 hours of treatment , the boy 's digestive tract has stopped bleeding , and his acid and electrolyte levels have returned to normal .

The family said they earn around 5,000 yuan ( $ 780 ) per year from a small plot of land . `` We sent him to the repair shop because our family is close with the owner , '' said the grandfather . `` Since his mother passed away , his dad hoped the owner of the repair shop could take care of him . We think of the owner as the boy 's guardian . '' The repair shop owner did not pay him money but bought him clothes and other items , according to the grandfather . He said the teenager does not actually work there but helps with simple tasks . China Daily reported that his treatment at the first hospital , in Shandong , cost about 100,000 yuan , and that the repair shop owner paid for 60 % of it . Angel Mom said it has received over 400,000 yuan in donations for the boy but has since suspended the donation drive , as the money seems to be enough for his treatment for now -- it would start accepting donations again if more funds are needed . The family said Du 's father had received 101,500 yuan of the donations so far . Deadly ax assault in China spurs online buzz . CY Xu contributed reporting from Beijing .
