An unlicensed syndicate behind hazardous electrical work across Sydney may be linked to a man’s death and a separate house fire, police have warned.

St George Police Area Command officers launched investigations into both incidents which occurred last year, and detectives have now released the images of two men who may be able to assist with their inquiries.

The syndicate has been offering homeowners across Sydney cheap wiring and unmetered access to the power grid, police said.
