A petrol station near Hamilton was robbed and the assistant assaulted on Sunday morning, while a man was violently set upon by a group of youths in Hamilton city centre the previous week, police say.
Waikato Police said early yesterday morning a BP petrol station assistant was assaulted by three people armed with a metal bar and hammer.
Three people entered the station in Horotiu, just off the new bypass interchange north of the city, around 3.15am after threatening the sole attendant to open up.
The attendant was assaulted, and then hid while the young offenders stole cash and cigarettes.
The suspects were driving a stolen white Subaru sedan with the registration number JWZ71. The car was recovered on Thomas St, Ngaruawahia, shortly after the robbery and with its engine still running.
