The home was believed to belong to an elderly couple.
A woman, whose house backed on to the property, said she did notice what now seems like some suspicious behaviour on Saturday.
She saw some strange people on her driveway, who immediately left when they spotted her.
Detective Inspector Corrie Parnell said police and forensic specialists were currently carrying out an investigation into the Stanbury Ave house.
Another property in Russley's Oakhurst Place, would also be investigated today.
Parnell said police were making good progress with information supplied by the public but asked anyone who had further information to come forward.
