One of the teenagers told police that although he was not threatened directly with the bottles he feared he was going to be stabbed, the Royal Court heard.
Serial violent offender Ruben Miguel Rodrigues De Freitas (24) and his friend Grant Barry Felix Hepburn (23), who is a father, both pleaded guilty to charges of affray.
De Freitas later told police he had vowed to get ‘revenge’ on one of the teenagers who he claims attacked him after learning that De Freitas had spent the night with his girlfriend.

During the hearing on Friday, Crown Advocate Sara O’Donnell told the court that Hepburn first came across the teenagers while walking down King Street at around 2.45 am on Sunday 19 April.
Hepburn later rang De Freitas who met him near Snow Hill with a full bottle of wine and a litre bottle of vodka.
After an altercation witnesses told police that the defendants started to ‘run’ at the group while carrying the bottles which they had smashed.
Hepburn later sent messages to one of the teenagers on Facebook, via a phone that police discovered was stolen, threatening him by saying ‘I’ll do time for you’ and suggesting the recipient was a ‘dead man’.
De Freitas, who is unemployed and lives with his parents, was sentenced to a year in prison.
Hepburn, who also pleaded guilty to charges of breaching the peace, sending a threatening message and theft, was sentenced to 12 months and two weeks.
Advocate Adam Harrison, defending De Freitas, said his client had no intention to use the bottle as a weapon.
‘He accepts that his actions would have been frightening to those who witnessed them.
Advocate James Bell, defending Hepburn, said: ‘He knows his behaviour was completely unacceptable, he knows the charge is serious but it is my submission that this is not the most serious offence of its kind.’
Commissioner Julian Clyde-Smith, who was presiding over the case, conceded that this incident was at the lower end of the scale for affray but said the court could did not take violent offences on Jersey’s streets lightly.
‘We have considered all the mitigating factors but we see no other option to a custodial sentence.
Jurats Suzanne Marrett-Crosby and Rozanne Thomas were sitting on the case.
