Whipsnade Zoo will face "no further action" following an incident in which a zookeeper was seriously injured after being trampled by a rhino.
The man, in his 50s, was tending to the animals in the Asian rhino enclosure last November when one of them unexpectedly turned on him.
He was left lying in water with injuries to his chest, abdomen and pelvis.

He was taken to Adenbrooke's Hospital in Cambridge where, at the time, he was described as being in a "serious" condition.
An investigation carried out by the Central Bedfordshire Council has now found there should be "no further action" taken against the zoo over the incident.
Speaking to Luton Today, a council spokesman said: "We have worked closely with Whipsnade following the incident and offered advice and recommendations around improving policies and procedures.
"We will continue to work with them on all aspects of health and safety.
"Following a lengthy investigation and review of the information gathered, no further action is to be taken."
According to the BBC, the zoo said it would not comment on the keeper's health, and the council said it would not be releasing more details as much of the information obtained was "subject to strict disclosure rules".
