Thieves have stolen hundreds of thousands of dollars worth of stock from a high-end boutique store in Melbourne’s east.

The front windows of Grace on High Street in Armadale were smashed about 4.45 this morning, before a group of three thieves entered the store.

CCTV footage shows one thief using a weapon similar to a pickaxe to smash a jewellery cabinet, while others raided clothing racks.

Police estimate $400,000 of designer women’s fashion was taken, but the boutique is still tallying the exact value of the stolen goods.

The group left the scene in a silver car, heading eastbound on High Street, police said.

It’s understood to be the second burglary at the store this year, after thieves allegedly stole jewellery from the store last month.

The boutique hopes to reopen tomorrow.
