It is believed the young man slept there overnight.
"It's very bizarre behaviour. It doesn't appear that he's actually stolen anything or there was any motive to steal anything," he said.
"It would appear [the victims] were away for some period of time before they have returned home".
Police believe the man entered as a squatter rather than to steal items.
Nothing was stolen and nobody was injured, but it was certainly a very bizarre break and enter.
The man is believed to be of Middle Eastern appearance with thin, dark eyebrows, an unshaven face and a script tattoo on the left side of his chest.
During the incident he was wearing a black New York Yankees cap and black shorts.
