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."

Wow, that's so sad.

What a nightmare! Poor guy, and to see them walk away too!

The surgeons will most likely replace the missing part of
his skull with some type of material, which will serve as
a protective barrier and hopefully improve his self-esteem.

OMG! How awful. If it had happened to a politician or a member of the police force they'd be looking harder for the culprits!

Poor man !!

how awful!
