A former North Korean defector who made a risky and rare cross-border return home last week had struggled in South Korea, officials and media reports said on Tuesday.

South Korea’s military identified the man who crossed the heavily armed Demilitarised Zone separating the two Koreas on Saturday as a North Korean who defected to the South in a similar area just over a year ago.

The man’s plight shed new light on the lives of re-defectors and raised questions about whether they had received adequate support after making the dangerous journey from the impoverished, tightly controlled North to the wealthy, democratic South.

The re-defector was in his 30s and making a poor living while working as a janitor, a military official said.

I would say he was classified as lower class, barely scraping a living, the official said, declining to elaborate citing privacy concerns.

Officials, who said they saw little risk of the man being a North Korean spy, have launched an inquiry into how he evaded guards despite being caught on surveillance cameras hours before crossing the border.

North Korean officials have not commented on the incident and state media have not reported it.

Little Interest in the Newcomer's Fate

South Korea’s Yonhap news agency reported police in the northern Seoul district of Nowon who provided safety protection and other care to him raised concerns in June over his possible re-defection, but no action was taken due to a lack of concrete evidence.

Police declined to comment. An official at Seoul’s Unification Ministry handling cross-border affairs said on Tuesday the re-defector had received government support for personal safety, housing, medical treatment and employment.

The man had little interaction with neighbours, and was seen throwing away his belongings a day before he crossed the border, Yonhap reported.

He was taking out a mattress and bedding to garbage dumps on that morning, and it was strange because they were all too new, a neighbour was quoted by Yonhap as saying. I thought about asking him to give it to us, but ended up not doing that, because we’ve never said hi to each other.

As of September, around 33,800 North Koreans had resettled in South Korea, daring a long, risky journey – usually via China – in pursuit of a new life while fleeing poverty and oppression at home.
