Port Elizabeth - Post mortem results show that 76-year-old Duncan Lethbridge of St Francis Bay in the Eastern Cape died as a result of suffocation after a home invasion last week, Eastern Cape police said on Tuesday.
Police spokeswoman Gerda Swart said a 35-year-old suspect was arrested in Humansdorp on Monday and charged with Lethbridge's murder and house robbery.
The elderly man, his wife and their housekeeper were assaulted when suspects ransacked their home last Thursday. Lethbridge was later found dead, his hands bound and mouth covered with sellotape.
The housekeeper was allegedly working outside the house when she was approached by two unknown men armed with firearms who pushed her inside before tying her and her employers up.
Two hours after the incident the housekeeper managed to alert neighbours who immediately called ambulance services and the police. The neighbours discovered the elderly man lying face down in the living room, hands still bound and mouth covered, and when paramedics arrived on the scene they declared him dead.
