A leisurely walk turned tragic for a woman and her two dogs on Crown Street in Surry Hills when one of the pets was tragically electrocuted after stepping on an electrified manhole.

Witnesses described the heart-wrenching scene as the surviving dog, a black Staffordshire Bull Terrier named Ninja, mourned its sibling by refusing to leave its side, howling for hours.

Authorities later identified the source of the deadly incident as an exposed wire emanating from a defective underground link box.

“We deeply regret and extend our heartfelt apologies and condolences for this tragic incident,” stated Deon Apps from Ausgrid.

“We’d like to extend our sincere apologies and condolences to the unfortunate incident that occurred,” Deon Apps from Ausgrid said.

“From what we know, we think it’s an isolated incident.”

Pouring rain likely created a pathway from the live wire to the lid’s metal rim.

For more than 15 minutes, people unknowingly walked over the live circuit before it was cordoned off; they were saved only by the rubber soles of their shoes.

The council is investigating the cause of the incident, only a few weeks after the footpath was opened after being redeveloped.
