Vicious thugs attacked a group of students walking home from a firework display, leaving one with a broken jaw and another with a broken nose.
Police are appealing for information after the four students were seriously assaulted by three youths on the Oak Park Estate in Northarbour Road, Cosham.
One of the teenagers was left with a broken jaw, and has since needed metal plates to be inserted into his face.
He is still unable to talk.
Another student suffered a broken nose after she was pinned down and punched in the face.
The attack happened at around 8.45pm on November 6, after the firework display at the King George V playing fields.
Hampshire Constabulary has only just released details of the incident.
Detective Constable Samantha Hockley said: ‘There were lots of people in the area due to the firework display.
‘We are keen to speak to the drivers of a small black car and a yellow cab type works van who were in the vicinity.
‘The drivers of these vehicle had cause to beep their horn at those who had been assaulted as they were crossing the main road near to Lakeside.
‘These drivers are possible witnesses and would appeal for them to contact police.
‘We would also like to contact a passing family that one of the students tried to warn, they may have seen the offenders.’
One of the suspects is described as a white boy, around 16 years old, with bad acne and pock-marked skin, short dark hair. He had a bike.
The second suspect was a white female, with bleached blonde hair and extensions worn up, wearing a navy hooded top.
The third suspect is described as a white female with dyed red hair, a dark-coloured hooded top and dark-coloured leggings.
Anyone with information should contact DC Hockley at Fratton CID on 101.
