A shocked mother is warning that central Auckland is unsafe at night, after her family was targeted in an unprovoked attack that left five people injured, NZ Herald reports. A gathering of 13 family members and friends – including an elderly grandmother – had been celebrating a 50th birthday party at a karaoke bar on Wyndham St in the early hours of Saturday morning, when they were ambushed from behind by a group of men wielding hammers and bottles. Her son, brother-in-law and niece’s boyfriend sustained injuries.
