Sydney teen stabbed to death

A teenager has died after being stabbed during an armed confrontation in Sydney's southwest.

Emergency services were called to Stranraer Drive, St Andrews, just before 2am after reports the 17-year-old had been injured.

Paramedics found him lying stabbed in the street and took him to Liverpool Hospital, where he died a short time later.

A police spokesman said it is thought the teenager was hurt during a confrontation between two groups of men. Nobody else was injured.

A crime scene was set up and detectives investigating the death are canvassing the neighbourhood.
