(15.5.2017) The issue of DNA collection has received some press attention. In one case in Shandong province, police collected DNA from more than 5,000 male students in one college in October 2013. The students were given no explanation about why their information was taken, and many “did not understand nor felt comfortable about it.” When reached by journalists, the school said it was to cooperate with the police’s request to establish a database about migrant populations, but the police said it was to solve a number of theft cases on the campus.
