( CNN ) -- Chinese health authorities have promised an overhaul in hospitals across the country following the arrest of an obstetrician for allegedly selling newborns to human traffickers , state media reports . Police in Fuping County in China 's northwestern Shaanxi Province said that the doctor in question , Zhang Shuxia , had allegedly sold other babies to traffickers in the past . Police were investigating 10 similar cases at Fuping County Maternal and Child Health Care Hospital , where Zhang was deputy director of the maternity department , reported state-run CCTV . The latest baby was returned to its parents amid emotional scenes on Monday , after its identity was confirmed through DNA testing . As family members wept , the parents knelt to thank police for recovering their son , the state-run China Daily reported . Fuping County authorities said the baby boy had been allegedly sold for 21,600 yuan ( $ 3,527 ) by Zhang on July 17 , the day after he was born . The baby was then sold two more times in ten days . Police said Zhang had allegedly told the child 's parents , Dong Shanshan and Lai Guofeng , that their son had contracted syphilis through the mother , and convinced them to surrender the boy into her care , reported the state-run People 's Daily . But when the mother subsequently tested negative for syphilis , she grew suspicious and reported what had happened to police . The infant was eventually found in a good condition in a town in neighboring Henan Province Sunday . Zhang and five other suspects have been detained on suspicion of human trafficking , reported Xinhua . CCTV cited six other alleged trafficking cases involving Zhang dating back to 2006 , including a pair of twins earlier this year . Health issues cited by Zhang in convincing the parents to surrender their children included heart problems , cerebral palsy and missing genitals . It reported that most of the affected families hailed from the village of Xue in Fuping County -- the home of Zhang and her mother . Another couple from the area told CCTV Zhang had convinced them to give up their baby son at the hospital in 2008 , after telling them shortly after the birth that the infant had stopped breathing . `` The whole delivery was around 10 minutes , natural birth . And then she came out and told me that the baby was n't breathing , '' recalled Dong Pengfei , the father . `` I was overwhelmed by that time , and I did n't have second thoughts . But after that I 've been thinking why she would refer to it as a 'kid ' if it was n't breathing . '' `` I could n't stop crying ever since I gave birth to my boy , '' his wife told CCTV . `` I feel like crying when I see kids from other families . '' China 's state health commission has called for severe punishment for those involved . `` ( The commission 's leadership ) see it as morally degraded , illegal and intolerable , '' said Mao Qunan , spokesman for the National Health and Family Planning Commission . The commission vowed to impose stricter management of medical services and implement stronger ethics training across the country to prevent similar cases .
