(CNN) Police rescued 37 babies and a 3-year-old girl after busting a child trafficking ring in eastern China's Shandong province, reported the state-run China Central Television.

The newborn babies, many suffering from HIV/AIDS and malnutrition, were sold for between 50,000 yuan to 80,000 yuan ($8,000 to $12,912 dollars). The boys fetched higher prices than girls, according to the online video report published on Tuesday.

Babies were often transported in large handbags and suitcases to prospective buyers. And they were allegedly fed instant noodles and leftover vegetables, according to Chinese state media.

Authorities have arrested 103 people, suspected of trafficking or purchasing the infants.
