Police have arrested a 64-year-old Singaporean man in connection with the death of 37-year-old Dexmon Chua Yizhi, whose body was discovered at the vicinity of Lim Chu Kang Road on Jan 1.

The arrest of the suspect on Jan 8, comes after 53-year-old Chia Kee Chen was charged in court on Jan 2 with the murder of Mr Chua at a multi-storey carpark at Block 429A, Choa Chu Kang Avenue 4, between Dec 28 and 29 last year.

Mr Chua's body was found hidden in thick and tall grass near Sungei Gedong Camp on New Year's Day after the police entered the restricted area during a search.

His family filed a missing person report when he did not return home after leaving the previous day. He was last seen along Cheong Chin Nam Road in Bukit Timah according to closed-circuit TV footage from a restaurant in the area.

The police said last week that they are also looking for an Indonesian man in his late 20s, identified as Djatmiko Febri Irwansyah to assist in investigations but preliminary investigations revealed that he has since left Singapore.

Anyone with information on Djatmiko Febri Irwansyah should contact the police at 1800-255-0000 or submit the information online at www.spf.gov.sg/CrimeStopper. All information will be kept strictly confidential.
