A great grandfather has been attacked in the front yard of his Two Rocks home.

The man was taking photographs of cars being driven illegally through sand dunes when a driver turned on him.

The 65-year-old was allegedly punched in the face outside his home.

“The ambulance bloke said to me, one punch people rarely get up ...you know, I wasn’t even thinking of that,” the man said.

He said he was trying to take pictures of the car’s number plates before the situation turned nasty.

It is illegal to drive in the dunes opposite his home and the land is privately owned.

“I was just taking photos of them, next thing I know I’m being attacked,” the man said.

His neighbour Tahla Cragg found him laying in a pool of blood.

“They charged at him and one punched him, they’d cut his face and he hit the floor really hard,” Ms Cragg said.

The man’s phone was smashed and a precious necklace, with his baby daughter’s ashes inside, was viciously ripped from his neck.

Residents say the problem with four wheel drivers that come through this area, is that they become lost in the sand dunes and the bush. They can’t find their way back to the main road, so they smash through the fence.

Today City of Wanneroo Rangers blocked the illegal access track in the dunes.
