Helicopter Over Niles

Around 5:30 this afternoon, Regional Parks copter Eagle 6 was called in to the Alameda Creek Trail area in Niles apparently by ground units to locate a few kids either in the creek or nearby ponds.  The kids were reportedly exiting the scene on bicycles and the ground unit was unable to locate them.  The helo crew said they did not see them in the water but were probably the kids in question.  Flight tracking data shows that the copter returned to Quarry Lakes around 20 minutes later, but I have no info on that, but may be the same.
