Lisburn Police are investigating a serious assault during which a young man was hit over the head with a glass bottle.
The assault is believed to have happened in the Sloan Street/Young Street area of the city at around 2.45am on Sunday, October 16.
A PSNI spokesman said the teenager was taken to hospital for treatment to a wound on the back of his head.
Officers from the D Section Lisburn Local Policing team are investigating the incident and have appealed for anyone with information to contact Lisburn PSNI on 101 quoting reference 283 16/10/16.
Lagan Valley DUP MLA Edwin Poots condemned the attack on the teenager, saying: “Obviously this sort of incident is something that we deplore and it’s not what we want to see happening in the local area. The Co Down side of Lisburn is a very settled community and population and that’s how we want it to remain.”
