Inside remarkable 'apartment' allegedly created by Sydney building manager under units

The remarkable set-up created by a Sydney building manager allegedly living underneath his apartment complex and using the space to store stolen goods and set up a cannabis crop has been revealed.

Jaden Hati, 42, was arrested on August 18, three weeks after police found an elaborate "cave" in a storage area in the basement of the Pyrmont apartment complex on Bowman Street.

Officers found shelving systems used to store more than 250 items stolen from other storage units, including electrical, sports and garden equipment, police said.

They also found a rainwater tank that had been converted into a bedroom and another tank that was being set up to grow hydroponic cannabis.

Police video recorded in the bunker-like makeshift apartment showed a fully tiled shower and separate toilet.

The rock walls were painted white in the bathroom area, and a toilet brush and can of air freshener on top can be seen.

A kitchen set up with a stainless steel sink, cabinets and a burner was also found by police. A cheese grater sat in the kitchen, while other personal items such as Wet Wipes, soap and a hairbrush could also be seen.

There was even a laundry area with a washer and dryer.

The building manager is due to appear in the Sutherland Local Court on September 30 charged with a raft of offences, including receive property, conspiracy to cultivate cannabis for commercial purpose, and goods in personal custody suspected of being stolen.

The basement discovery on July 29 came three days after three men were arrested at a Lane Cove home.

Police seized items including a crossbow, an extendable baton, and a pair of throwing knives.

Two of the men - aged 26 and 33 - are before the courts on drug possession charges.

A 24-year-old man has been charged with drug supply, six counts of possessing a banned weapon, and possessing suspected stolen goods, among other offences.
