MACEDON Ranges Crime Investigation Unit detectives are investigating the theft of tools from a cafe in Mount Macedon last month.

Police allege the offenders arrived at the Cameron Drive address just after 4am on Wednesday, February 10, before entering the business by forcing a door lock.

The men gained access to an external storeroom where they stole a water pump, pressure washer as well as other power tools and items.

Police have released pictures of three males they believe could assist with their enquiries.

Anyone with information is urged to contact Crime Stoppers on 1800 333 000 or submit a confidential report online at www.crimestoppersvic.com.au.
