A THUG who “violently and deliberately” threw a chemical in his teenage victim’s face has been jailed for 11 years.

Jack Psaras threw the corrosive fluid in the Nicholas Brown’s face without warning outside a pub in January this year.

The dad-of-three had admitted grievous bodily harm but denied carrying out the attack with intent.

But after just two hours a jury found the 32-year-old guilty at Chelmsford Crown Court.

Judge Turner QC took the unusual step of sentencing Psaras straight away.

Sentencing him to 11 years in jail, he said the attack is “just the type of nightmare that haunts anyone who goes out to socialise in a pub or club”.

He added: “No sentence I pass will fully repair Mr Brown’s vision. He will live with the consequences almost certainly for the rest of his life.

“You have rightly in my judgement been convicted of a grave assault on a wholly innocent person.

“As a result of what you did, Mr Brown suffered severe chemical injury to his right eye which seems to have gravely impaired his vision.

“Unlike many other acid throwing cases as Andrew Newton [defending] observed are in the newspapers, this hasn’t caused any cosmetic deficit, but is nonetheless an injury of extreme gravity.

“He’s lost confidence as a driver as a consequence of your actions and his injury is very likely to be life long.

“It was sudden, unprovoked, unexpected, random violence of a serious nature.”

The category one offence carries up to 16 years in prison, starting at 12.

Andrew Newton, defending, said this lengthy custodial sentence will lead to the inevitable loss of contact between him and three children, aged 14, 13 and nine, from a previous relationship.

Judge Turner said this is “tragic” but the father had “failed his children by his chosen criminal lifestyle”.

Psaras has 33 convictions for 56 offences, ranging from knife offences to harassment, drugs and assaults on police officers.

CCTV footage outside the Bath House pub from January 20 showed Psaras throw liquid at 18-year-old Mr Brown while he held on to another bottle of alcohol in his left hand.

Witnesses told the court the two groups of pubgoers were strangers but were socialising inside.

After the attack, Psaras immediately left with friends while the victim rushes inside where cameras captured him desperately washing off the substance.
