Two men impersonating police officers have used the ruse to rob a woman in her home on the NSW Central Coast.

Police say the men visited the Gorokan home of the woman at around 11pm on Monday, telling her they were police officers from a specialist command.

When the woman let them inside they took three laptops before leaving in a silver Holden Commodore.

They are described as being white, in their early 20s, between 170cm and 180cm tall and with average builds. One of the men is described as having short, dark blonde hair and blue eyes.
