Two men were assaulted by a group of teenagers in Hamilton overnight in what police called a "cowardly attack".
Senior Sergeant Mike Underwood said police were called to the corner of Anglesea and Ward streets about 2.38am.
"It appears two young men, who had walked into the CBD from Hillcrest to catch a ride home with a friend who was finishing work, were set upon by a group of males and had their backpacks stolen in Garden Place," Mr Underwood said.
"As a result of the assaults both men are now in Waikato Hospital under observation for a variety of injuries ranging from scrapes and bruising through to a neck injury, broken collar bone and concussion."
He said police found a group of males in an alleyway on the Wintec Campus nearby.
