JOHOR BAHRU, Oct 16 — Two Tenaga Nasional Berhad (TNB) contractors were critically injured after suffering electric shocks during maintenance work at the utility company’s Kangkar Tebrau main intake substation here this evening.

The incident triggered a fire and disrupted electricity supply in parts of Johor Bahru.

TNB said the fire broke out at 6.03pm, interrupting power supply in several areas around Johor Jaya and its surrounding areas.

“TNB’s technical team has been deployed to the site and is actively working to restore electricity supply to the affected consumers,” the electricity company said in a statement.
