DAEGU (Yonhap News) ― Police said Sunday they have arrested a middle-aged man suspected of setting fire to the birthplace of ex-president Roh Tae-woo.

The 44-year-old man, surnamed Baek, is suspected of setting fire to the house where Roh was born in the southern city of Daegu around 4:05 a.m. on Dec. 12, according to Daegu Dongbu Police Station.

The fire slightly scorched part of the house, leaving only minor damage, police said.

Police interrogation has so far found that Baek was arrested in 2007 for vandalizing a historic tombstone in Seoul. They are further questioning the man, the police station said.

Roh, a former Army general, served as president from 1988 to 1993.
