A hunt is under way to identify a man seen on CCTV footage after the bomb squad detonated several explosives located in a Melbourne home earlier this year.
Police were called to a short-term Belle Vista rental in Keilor East on January 24 following reports a cleaner had stumbled upon a number of suspicious items, including explosives, guns, $1 million in cash and a "large quantity" of drugs.
Investigators believe the items may be linked to organised crime.

The Bomb Response Unit attended the scene at the time and safely detonated several incendiary devices.
The property had been booked for several weeks in January and investigators identified a white Toyota Camry hire car that travelled back and forth from the address during the rental period.
A man is pictured on CCTV filling up the Camry at a petrol station on Western Ring Road in Ardeer South on December 25.
Police want to speak to the man seen in the footage and urge anybody who recognises him to come forward.
The Camry was seized by police on January 24 and returned to the hire company.

The man in the CCTV is not the man who hired the car, police added.
Investigators said the man who hired the car has been spoken to but "has not been co-operative".
"I would urge anyone out there who recognises this man or who has any information on the items located at this accommodation to do the right thing and come forward," Major Drug Squad Detective Inspector Jamie Walker said.
"This was not a run-of-the-mill seizure of drugs and cash – there were incendiary devices and a large quantity of firearms.
"This is organised crime.
"We will track down those responsible and hold them to account. It would be in your best interests to tell us what you know now."
Anyone who recognises the man in the CCTV or with any further information is urged to contact Crime Stoppers on 1800 333 000.
