WA Police have been left red-faced after a thief stole nearly 100 cannabis plants from under their noses in Perth's southern suburbs.
Police attended a semi-rural home in Anketell after they were tipped off about an alleged cannabis cultivation project on the property.
![It's understood hundreds of cannabis plants were found at the Perth home.](http://web.archive.org./web/20180117154850im_/https://www.fairfaxstatic.com.au/content/dam/images/h/0/c/q/4/g/image.related.articleLeadwide.620x349.h0iq4d.png/1516008147969.jpg)
An initial search of the house found a large number of cannabis plants being hydroponically grown inside building structures at the home.
Officers arrested a 61-year-old man and a 41-year-old woman at the property, and charged them with growing the plants.
While police investigated, they established a crime scene and officers were assigned to guard the property overnight.
However, when police executed a search warrant the next morning, they found the scene had been breached and around 100 cannabis plants removed from the property.
As a result, the Internal Affairs Unit is now investigating how people were able to get into the property and steal the cannabis plants.
The Organised Crime Squad is also investigating the theft of the cannabis plants and a range of serious drug offences linked to the property.
The two people charged were remanded in custody and will appear in the Perth Magistrates Court on Tuesday.
