BEIJING - More than 300 people were arrested in China for telecom and Internet fraud in 2015, but outdated laws are struggling to keep up with the development of this high-tech crime, the Supreme People's Procuratorate (SPP) said on Thursday.

Police are seeing a rise in cybercrime, including transnational cases, and the sums of money involved, increasing the threat to state and public security, said the SPP.

"It is becoming more difficult to fight Internet crime as new types of it emerge. Moreover, outdated laws and regulations have obstructed the crackdown," according to a statement.

It said the SPP has been releasing judicial interpretations to aid prosecution of new types of cybercrime.

Of the 334 suspected fraudsters arrested last year, 329 have been prosecuted, according to the SPP.
