Binge-drinking Luke Gorman got tanked up and attacked staff - including the chef - just two days before he was due in court for launching a brutal unprovoked assault on a trolley collector.

The 18-year-old lout had an extra nine months slapped on his sentence and was branded "downright nasty" by Judge Paul Tain yesterday (Monday).

Brighton Crown Court heard jobless Gorman punched and kicked dad-of-two Paul Gurr into a coma as he collected trolleys in the car park at Tesco in Bexhill, East Sussex, on October 20, 2006.

Mr Gurr, 39, was left with skull fractures and brain injuries after Gorman, who had been drinking, stamped repeatedly on his head. One of his eye sockets was so badly beaten it had to be rebuilt with metal plates.

His injuries were so bad he missed the birth of his daughter five days later - despite being in the same hospital.

Gorman, who was just 16 at the time of the sickening 'frenzied' attack, admitted GBH and was bailed to January 17 this year for sentence. He was told to expect a lengthy jail term.

But two days before his appearance, Gorman decided to 'go out in style' and drank strong lager, alcopops and shots with pals during an all-day booze binge, the court heard.

Prosecutor Walton Hornsby said: "In the evening, he and his group went to the East India restaurant in Bexhill. At this point, they had already been drinking for some time.

"Gorman insisted on being served drink without food, which staff told him they would not do. The manager, who is in his 50s, remonstrated with him, but he became aggressive and lashed out with his fists.

"A waiter jumped in to help, but Gorman continued to be aggressive, so the chef got involved."

After punching the chef in the face, breaking his glasses, Gorman chased him down the street shouting obscenities. He then returned to the Sackville Road restaurant, where the manager was on the floor, and stamped on his leg - breaking his ankle.

Kim Goodall, defending, said: "He had been drinking all day to celebrate his 18th birthday and to mark his last few days of liberty before the start of his inevitable lengthy prison sentence."

The court heard Gorman, of Gwyneth Grove, Bexhill, was given a two-year detention and training order in a youth offenders' institute on January 17.

Yesterday, he was given an extra nine months after admitting two counts of ABH and two of common assault.

Judge Paul Tain told him: "One thing is abundantly clear - you are a downright nasty drunk.

"You knew you had a problem with drink, but you drank anyway. The consequence was that you attacked several innocent people in an Indian restaurant.

"You also have general anger management issues which must be dealt with."
