Steve Gator, 26, has been told the teenagers who ambushed him will not face court after British Crown Prosecution Service dropped the case.
The CPS said it did not have enough evidence to proceed but Steve's mother, Nina Gator, expressed her disbelief at the decision.
"Our boy is
walking around with half a head -- what more evidence do they need?" Nina Gator told SkyNews. "I can't believe it."
Steven Gator, from Essex, Great Britain, was left seriously brain damaged following the attack as he made his way home from work on January 15.
The two thugs started screaming taunts and abuse at him about his cousin but when he confronted them he was hit so hard he fell back and smashed his head on the pavement.
He was left in a coma for two weeks and his brain swelled so much surgeons removed the front half of his skull just hours after he was admitted.
He now suffers frequent seizures, has difficulty talking, and lost much of his memory.
Mr Gator now lives with his mother, who is his main carer as he can no longer work.
Mrs Gator said: "He's just a different boy. His sparkle is totally gone. He used to be so independent but he can't work any more and he can't drive. He's got half a head and he's completely lost his confidence.
"There's absolutely nothing protecting his brain now - it's just under his skin. We're waiting for surgery for a new skull plate to be put in."
A Havering police spokesman said they had no plans to look for any other attackers in connection with the case, adding: "We gave the
CPS all the evidence available and after reviewing the case they decided not to proceed with it. We adhere to their decision."
Corrine Soanders, the Crown Prosecutor for Havering, said: "Once the CPS had been supplied with all the necessary evidence relevant to this case, a full review showed there was insufficient evidence to provide a realistic prospect of conviction.
"This is a key test which must be met to bring a prosecution and in light of this, the case against the two defendants was discontinued. I apologise to the victim and his family for not conveying this decision to them personally.
"I welcome any questions they may have and will be contacting them shortly to offer further explanation."
Words cannot describe wh...I just hope someone seriously and I mean seriously makes those two ****ing dirtbag pieces of **** scum ****s teens pay.
and yes, I am actually crying.
