Police in the Humansdorp cluster have arrested a 35-year-old suspect in connection with the murder of an elderly resident from St Francis Bay.
Spokesperson Captain Gerda Swart says the 76-year-old Duncan Lethbridge died following a house robbery last week where he was tied up with his wife and housekeeper.
She says the post mortem results are not yet available for Mr Lethrbridge but confirmed that the suspect will be charged with house robbery and murder.
Swart says more arrests are expected soon.
Lethbridge and his 71-year-old wife were tied up in their home in Sardinia Road shortly after their housekeeper was accosted by two armed suspects last week.
Swart says the intruders tied up all three victims before ransacking the house.
The housekeeper managed to alert the neighbours a few hours later who immediately called the ambulance services and the police.
Lethbridge's body was found in the living room where he was declared dead by paramedics.
His hands were still bound and his mouth covered in sellotape.
