Two off-duty Vic cops bashed on NYE

Two off-duty police officers were seriously assaulted after they tried to stop a group of people letting off illegal fireworks in Melbourne on New Year's Eve.

The two female officers approached the group in Brunswick just before midnight on New Year's Eve after they noticed them using illegal fireworks, a police spokesman said on Wednesday.

A fight then broke out in a nearby alley and one of the officers was knocked unconscious while the other suffered serious facial injuries.

Both were taken to the Royal Melbourne Hospital in a serious condition, but they have since been released.

Police are investigating the incident which is believed to have involved local residents.
