“Eagle responded and located the bike being driven at excessive speed on the Northern Busway southbound.
“The bike has continued to be tracked by Eagle, as it exited at Constellation Station, making its way onto the Northern Motorway.”
The helicopter kept an eye on the 15-year-old rider while police on the ground held back.
McKeown said the bike was seen getting off the motorway at Tristram Ave, and heading for Beacroft Park.
“He has cut through a football game being played at the time, before heading towards Milford.”
The “reckless run” finished when the teen fell off the bike on Bevyn St, said McKeown.
He suffered no injuries but “did find himself in handcuffs and under arrest”, he said.
The teen has been charged with aggravated robbery, reckless driving and possession for supply of cannabis.
He will be appearing in the North Shore Youth Court today.
“We are ensuring the young victim is being provided by support after this unsettling event,” McKeown said.
“I’d like to acknowledge all the frontline staff, Eagle and our CIB investigators for their work in responding to this incident.”
