The entrance to Leicestershire Wildlife Hospital was blocked this morning due to fly-tippers disposing waste near the gates.
Old boxes, rubble and garden waste was strewn near the entrance, preventing staff and volunteers gaining access to the centre.
The hospital, on Fleckney Road in Kibworth Beauchamp, said it was not the first time that fly-tippers had struck.
They have reported the incident to the local authorities, who have begun to clear the waste away.
A spokesman for the centre said: “Yet again we have had a load of trash tipped onto our driveway to the hospital this time preventing the staff and volunteers getting through the gates of the premises. What’s wrong with some people.”
The hospital rescues and rehabilitates sick, injured, orphaned and distressed wild animals and birds throughout Leicestershire and the surrounding region.
