A police officer is in a serious condition in hospital after the arrest of a 16-year-old boy turned violent in northern Sydney.
Police said the teenager was acting suspiciously near the corner of Balaclava and Epping roads in Marsfield when he was approached by an officer about 10:00pm.
The teenager allegedly became aggressive.
After calling in two other police officers, the teenager allegedly kicked the policeman in the face, causing him to fall and hit his head on the road.
Anthony Elgood was leaving the neighbouring Macquarie University when he saw the aftermath of the alleged assault.
“I saw one police officer lying in the gutter and another man lying down … injured on the floor,” he said.
“I couldn’t see what happened but the police officer seemed to be fairly badly injured, he had headwounds by the look of it.
