Why are people throwing oBikes into the Yarra River?

Melbourne’s problem with oBikes being thrown into the Yarra River appears to be getting even worse.

3AW was sent this picture late last month, with at least a dozen bikes on a boat having been pulled from the river.

Ross and John were sent a picture this week, taken near the Morell Bridge.

“I was absolutely gobsmacked,” Bradley, who took the photo, told 3AW Breakfast.
