Brazen thieves made off with $80,000 worth of televisions in a matter of minutes in Eastern Creek last month.
Police have released security footage of the incident in the hopes of catching three men involved with the theft.
The footage shows a truck reverse through a roller door into the Kangaroo Avenue warehouse.
One man uses a forklift to lift pallets of televisions, while another climbs onto the back of the truck and loads the pallets.
Police said the incident took place about 11.30pm on Tuesday, February 14.
Mount Druitt police responded after staff reported the break-in at 6am the next day.
A State Crime Command spokeswoman said the warehouse was alarmed, and employees reported it was locked and secured the day of the break-in.
The incident is being investigated by Strike Force Seeliger, part of the Property Crime Squad’s Breaking Unit.
Property Crime Squad commander Murray Chapman said the break-in was targeted and well-planned.
“The CCTV clearly depicts an organised group, who know exactly what they are after, and moved swiftly to get in and out in a matter of minutes,” Detective Superintendent Chapman said.
“In this short period of time, the factory sustained thousands of dollars of damage, and the thieves got away with property believed to have a total retail value of the more than $80,000.
“While we are following a number of lines of inquiry in relation to the stolen televisions, we are hoping someone might recognise the men in the CCTV and help us identify them.”
It is believed the truck used to transport the stolen goods was stolen, while the forklift was property of the warehouse.
