An ex-convict who allegedly underwent surgery to change his appearance in order to continue carrying out burglaries has been arrested, authorities said Monday.

Police in Incheon, west of Seoul, said the 35-year-old man stole 530 million won ($480,000) worth of valuables from April to December 2014.

The man had undergone surgery to reduce his jaw size and lengthen his legs in an apparent attempt to conceal his identity, the Incheon Nambu Police Station said. The man, however, said the procedures were intended to boost his self-esteem.

A former worker in home decoration, he also used handmade tools to dismantle digital door locks at more than 80 apartments, authorities said, adding they are looking to see whether he had committed other crimes. (Yonhap)
