Police have been investigating the death of a Korean diplomat in Singapore who was found with multiple gunshot wounds to the head.

The State Prosecutor’s Office said the death happened on Monday at a residence in the western suburbs of Singapore after police received reports of a shooting at the residence.

A spokeswoman said the victim, who was a Korean embassy official, was taken to a Singapore hospital and was later transferred to a hospital in Kuala Lumpur.

Police were alerted to the incident by residents who said they saw a man with a rifle inside the residence on Sunday night.

Investigation continues to determine whether a weapon was used, the spokeswoman said.

Chand Palace is the residence of the former leader of Singapore, Lee Kuan Yew.

There is no indication that the victim was targeted in the incident, the spokesperson said. 

The death was the second in recent weeks of a senior Korean diplomat to die in Singapore, which was also the site of the murder of Lee’s father, the late Lee Kun-hee.

It is unclear how long the investigation would take.

Lee Kuan-hee, who died aged 87 in 2008, was the first Korean-born leader of the ruling Singaporean People’s Action Party (PAP) to be killed in Singapore.

In 2010, former Singapore Prime Minister Lee Hsien Loong was killed by a lone gunman.

Mr Lee was a key figure in Singapore’s democracy movement during the 1990s and helped develop the country’s first democratically elected leader, Lee Hock Chee.

Singaporeans have long expressed concern over rising crime levels, with the murder rate having been climbing for years.

Despite such concerns, Mr Lee’s killing was widely seen as a politically motivated killing by the PAP, which campaigned on a promise to eradicate the crime rate.

After the killing, Singaporean authorities said they would continue to focus on the issue of crime.
