A South Korean woman and her boyfriend were arrested for allegedly drowning the woman’s husband in 2009 in order to claim a large insurance payout.

Lee Eun-hae, 31, and her extramarital lover Cho Hyun-soo, 30, were arrested last week, The Korea Herald reported. The pair was accused of goading Lee's then 39-year-old husband to jump into a river in Gapyeong, causing him to drown. The victim did not know how to swim.

Investigators think the pair carried out the crime to gain a KRW800 million (SG$880,000) payout from the victim’s life insurance policy.

Prosecutors said that the suspects are also accused of two previous attempts to kill the husband earlier that year – poisoning him with puffer fish toxin in February and an attempted drowning at a fishing place in May.

The court granted prosecutors’ request to arrest Lee and Cho on charges of murder by nonfeasance, attempted murder and attempted insurance fraud.

The suspects had been in hiding since December, when the prosecution invited them for questioning. In late March, their identities were made public and they were placed on the wanted list.
