A man in his 50s has been apprehended by police after striking a woman in her 20s on the head with a stone while she was walking down the street late at night.

The Yongin Dongbu Police Station in Gyeonggi Province announced that it has arrested and is currently investigating a man identified as A on charges of special assault.

A is accused of striking a woman in her 20s, identified as B, on the back of the head with a stone, causing injuries, on a street in Yeokbuk-dong, Cheoin-gu, Yongin, at around 1:20 a.m. today.
