Beijing : A man who killed 11 people in China has been arrested, authorities said Sunday.
DNA evidence shows Zhang Yongming was behind the murders, the public security ministry said.
Fifty-six-year-old Zhang hails from Nanmen village in Yunnan province. All his victims were males, Xinhua reported.
Zhang was earlier convicted for a murder in 1979 but walked out of prison in 1997 after serving his sentence.
The probe shows Zhang attacked his victims when they were walking home alone on a deserted stretch near his house, where he lived alone since 2008.
After the murders, Zhang used various means, including dismemberment, burning and burial, to destroy the evidence.
