BUILDING site thieves used a copper pipe to attack a security guard at the 123-year-old Tukarua mansion in Cottesloe about 2.20am last Saturday.
The Marine Parade site is under renovation by iron ore magnate Andrew Forrest.
“As the guard advanced towards the suspect he threw the copper pipe at him, missing him, then all three suspects ran off,” Senior Constable Belinda Crafford said.
The heritage-listed mansion on 5001 sq m was bought by Mr Forrest in 2015 and it is currently undergoing renovations and extensions, including new homes at its front.
Const Crafford said the guard investigated when he saw freshly cut wiring hanging from a first floor in the compound and heard noises in the scaffolding above.
She said the guard chased a man from the scaffolding who attempted to hit him, before both men ran into the building’s basement, where there were two other men.
“The guard challenged all the men and advised them he was going to call police,” Const Crafford said.
One of the men raised the pipe and threatened to hit the guard with it, before it was thrown, and he and his accomplices ran off.
Constable Crafford said the lack of light meant there was not a clear description of the men.
