A mugging victim had his two front teeth knocked out when he and another boy were attacked on their way home from a house party in Cranbourne.
About 11.30pm on Thursday 8 January the two boys were walking down Fairfield Street in Cranbourne when they were approached by three males who were described as African in appearance.
Police believe these three men had been at the party uninvited.
One of the victims was kicked to the throat by a man who was described as tall and lanky wearing skinny leg jeans.
He also had spray directed at his eyes which caused him to lose vision and also burnt his lips.
The other victim was knocked out and police believe his wallet was stolen.
One of the victims will undergo significant dental repairs after his two front teeth were knocked out.
Both boys were taken to Casey Hospital and police have appealed for any witnesses to come forward or people who were at the same party.
