The 66-year-old woman, who asked to be referred to as “Nan”, said the incident occurred around 1am Sunday at her property in Eaglehawk.

The words “dead dog” and “dog slut” were written on the caravans and their tyres slashed.

Nan’s daughter, who asked not to be named for safety fears, she had recently received a bullet in the mail.

Nan said the vans were to be bought by a homeless family the following day.

“I don’t think I’ve ever been so scared,” she said.  

“I ran inside and locked up like Fort Knox.

“I didn’t sleep for the rest of the night, I kept peeping and looking out the window.

“I’m a grandmother and a great grandmother.

“I’ve got six grandchildren and seven great grandchildren and I sure don’t need this in my life.”

Police were contacted the morning after the incident and attended the scene.

A neighbour said they had seen people running from the property.

“Not only is it all such disgusting writing all over both the caravans, on one of them it’s also written ‘dead’ along floor and ‘slut’ across the door,” Nan said.  

“I thought they might have set fire to them and I don’t know what I would have done.”

Nan’s daughter said she had received threats on Facebook and believed the person involved may have been behind the incident.

“We’re 99 per cent sure it’s them,” she said.

“The wording on the caravan is the kind of stuff that’s been texted to me and sent on Facebook.

“We want the police to do a bit more and get them charged.”

She will have to have the caravans repainted and the tyres replaced before they can be sold. 

"The homeless people were going to look at it and hopefully purchase it and move in to a back yard," she said. 

"That won't happen at this stage."
