SINGAPORE - An 82-year-old man was arrested on Sunday (Sept 1) in connection with the murder of a 79-year-old woman in Toa Payoh.

The Straits Times understands from some neighbours that the two were not married but lived in the same flat for over 20 years.

Police said they received a call requesting for assistance at about 3.40am on Sunday.

Madam Lim Soy Moi was found motionless in a unit at Block 191 Lorong 4 Toa Payoh. She was pronounced dead by paramedics.

Retiree Madam Goh Leng Sim, 86, who lives below the unit, said she did not see the pair around much. She said the victim worked at Safra Toa Payoh McDonald's outlet and had two sons and two daughters.

Madam Goh also said she often bumped into Madam Lim when the latter was going out to exercise in the mornings.

ST visited the McDonald's outlet and confirmed that Madam Lim had worked there since 2013, but resigned a few months ago.

Police have classified the case as murder.

The suspect, Pak Kian Huat, will be charged in court on Monday.
