Coroner investigates NSW tradesman's death

A coroner will investigate the sudden death of a Sydney tradesman and any possible link to the illegal installation of satellite dishes.

The 24-year-old died while carrying out work in a roof in Sydney's southern suburbs in February.

Police are investigating whether his death could be linked to faulty wiring previously installed to illegally access subscription television channels.

NSW Police believe a previous occupant of the house may have requested the illegal work be carried out.

Detectives are working to uncover a syndicate that may be providing cheap, unlicensed electrical wiring services, including unmetered access to the grid.
