Carol Saldinack (51) is scared to even open her front door, unsure of who may be on the other side.

The daily terror began after she 'shopped' sons Luke Newman (27) and Oliver Clark (24) to police for helping attack father-of-two Marc Parkinson.

Mrs Saldinack, who grew up in Bognor Regis, told the Observer: "They ran away and left him in a pool of blood. How could they do that to someone? Even if they were drunk, that is no excuse.

"They have got to realise they can't do that to people."

They launched the unprovoked attack with Benjamin Hammond (25) after a night drinking in The Globe pub by Chichester railway station on June 9.

Their repeated punches and kicks left Mr Parkinson with a detached retina and scratch to the surface of his right eye, bruising and swelling to both eyelids, a cut lip, forehead and eyebrow, perforated eardrum and bruising to his ribs.

Mrs Saldinack, who lives in Norfolk, learned of her sons' vicious crime after they bragged about it to their sister Amber, who is now 18.

"They didn't want me to know because they probably knew I was going to 'shop' them," she said.

"I couldn't sit back and say nothing because that makes me as guilty as they are."

Since then, she has faced a barrage of verbal abuse from her family and sons' friends, and has been cut off from much of her family, meaning she can't see her five grandchildren.

And Newman has even threatened her life 'in anger' over the phone.

"He told me 'it might not necessarily be me but you might not wake up in bed one morning'," she said.

She is now on anti-depressants and says she and her husband have lost the will to live.

"I'm too scared to come home because I don't know what might happen," Mrs Saldinack said.

"I feel awful about what I have done but why should I apologise?"
