A tracker on a stolen laptop has led police to a drug and weapons bust in Melbourne’s north-west.

A woman reported her laptop was stolen from a car parked on Maidstone Street in Altona on Friday. 

The 37-year-old Altona resident had tracking software installed on the computer and was able to find its location. She told police the laptop could be somewhere on Holehouse street in Sunshine North. 

Detectives and the Operations Response Unit attended the street in search of the stolen laptop on Saturday and spoke to a number of residents before obtaining a search warrant for a particular house.

Police searched the property and found the alleged stolen laptop along with four guns, ammunition, drugs, cash and a conducted energy device. 

Three men were arrested at the scene. Two men, both aged 27, have been charged with firearms, drug, ammunition, weapons and property offences.

The other man, a 26-year-old from St Albans, was charged with firearms and drug offences and was bailed to appear at Sunshine Magistrates Court on 21 December.
