Police are appealing for witnesses following the theft of a life-sized fibreglass cow from a business in Truganina in April.

Police have been told that a silver Holden VE Commodore station wagon towing a trailer containing three offenders attended the business on Peterpaul Way on Sunday, April 27 at about 1.20am.

Two of the alleged thieves got out of the Holden wearing balaclavas and dark clothing while the driver and third offender remained in the vehicle.

The pair lifted and moved the fibreglass cow, named Betsy, into the back of the trailer before travelling east along Schembri Drive.

Betsy is red and white in colour and estimated to be worth $3500.

Investigators have released an image and CCTV footage of Betsy in the hope someone knows its whereabouts.
