“[Then] he was allegedly set upon by two people in the group. After assaulting the victim, they have taken a watch he was wearing and fled on foot.”
Police were sent to the scene, including a dog handler, Lautogo said.
“The police dog has begun tracking one of the alleged offenders and he was located in the nearby area. The 16-year-old male was taken into custody.”
Police were “following positive lines of inquiry” to find a second male involved, Lautogo said.
“This was a cowardly assault and the violent behaviour exhibited last night will not be tolerated.”
The victim was taken by ambulance to Waitākere Hospital for observation, but did not have serious injuries.
Anyone with information should contact 105 online or by phone, quoting the reference number 250806/9635.
In the Avondale incident, the young victim suffered moderate injuries.
In a Facebook post, he could be seen with injuries to his head and eyes.
Police are investigating the incident, which was about 1.30pm near a walkway that leads to Blockhouse Bay Rd.
