Arson Squad investigators are searching for some hero tradies that entered a burning bank in Springvale last week, Victoria Police say.
Police have released CCTV that shows two men in high visibility gear enter from the rear of the Springvale Road business and make their way through the smoke.
The men came to the aid of many of the customers and staff in the bank just after 11.30am.
Investigators have no doubt the men saved lives that day and are urging them to come forward so they can assist with the investigation.
A 21-year-old Springvale man remains in hospital under police guard.
Four members of public injured during the incident also remain in hospital.
Anyone with information is urged to contact Crime Stoppers.
