On illegal bikes were out on the field yesterday late afternoon. They were riding across the park and around the copses. I was with my dogs and had to keep to the edge. At one point a bike drove straight at us but then saw my Rottweiler and turned back. They have ruined the grass. They left litter all around the breeze block walls where they congregate as usual. The walls need demolishing and the park needs monitoring. It’s getting worse.
