The family of a Saffron Walden ­teenager killed in a car crash are “devastated” after their memorial was moved from the site of the accident.

Thirteen-year-old Joshua Bysouth died on September 18, 2011 alongside his grandfather Michael Kidd, on the A1307 near Linton.

After the accident, Joshua’s father Paul erected a small wooden cross at the site.

“It was incredibly important to me because I made it, and it was the last thing I could give my son,” said Mr Bysouth, a wood machinist by trade.

On Thursday, the family ­commemorated the third ­anniversary of Joshua and Michael’s death by placing flowers and gifts around the memorial.

When Mr Bysouth drove back from work on Monday evening, he found the memorial, along with the flowers and gifts, had been removed.

He said: “I was completely shocked when I saw it. The memorial was incredibly important to me and the whole family, it was the last little bit of my son.

“What sort of person would do such a callous thing? It’s just sick.”

Mr Bysouth said he at first believed the flowers and memorial may had been removed by the ­highways authority, but was told it had no knowledge of the removal.

“My ex-wife’s friend posted on Facebook that they passed the ­memorial Monday afternoon and the flowers were still there.

“So to do it in daylight and not be questioned ... I think it could have been the council.”

Cambridgeshire County Council also denied knowledge of the removal of the memorial.

Mr Bysouth has reported the case to the police, who are investigating.

He said: “Unfortunately, there’s very little they can do but they are looking into the matter. Hopefully, we can find out what happened.”
