“At this time, the officer who was driving the police car has been removed from frontline duties pending the outcome of these investigations.”
Home Secretary James Cleverly had asked for a “full, urgent explanation” as to why officers used the car to ram the escaped animal, saying it seemed “unnecessarily heavy handed”.
The animal, a 10-month-old calf named Beau Lucy, is “limping” but doing “a lot better” and taking medicine to treat her injuries, according to her farmer owner.
Online footage of the incident showed Beau Lucy in a residential street being hit twice by a police car, as a nearby member of the public shouts: “What are you doing that for?”
Beau Lucy got to her feet after the first strike and being thrown metres down the road, before being hit again by the car a second time.
She then remains on the ground, with her neck and top half of her body appearing to be stuck under the car. Officers then get out to assess the situation.
The force said it had been alerted by calls reporting that a car had been damaged and the animal was running at members of the public.
Deputy Chief Constable Nev Kemp added: “I know there is much concern around the current welfare of the cow. She is now back with her owner and recuperating with her herd.
“She did sustain a large cut to one leg and cuts and grazes. She continues to be monitored by a vet and our rural officers are staying in contact with the owner for updates.
“I can confirm that on the night, efforts were made to contact local vets without success and efforts were simultaneously being made to identify the owner.
“Why these were unsuccessful and what more could and should have been done will form a key part of the investigation.”
He said the police had acted out of a duty to protect the public and that animal welfare was important.
He said “we know people want answers about how this happened and what led up to it,” adding: “I am committed to ensuring that we have a full understanding of what took place and why, and we will fully support any investigation.”
It comes after Beau Lucy’s owner, a farmer who would only give his name as Rob, described the incident as “quite horrific” and “wrong” and said “it could have been handled so much better”.
Rob, who would not be drawn on whether the officers involved should face any disciplinary action, suggested that a vet should have been involved in Beau Lucy’s rescue, which may have avoided causing her distress.
He told PA news agency: “I think the video speaks for itself. It was quite horrific.
“The method of dealing with the situation was incorrect. It was wrong and I think that’s the message we’ve learned.
“I just think that there was poor communication, and they should have spoken to a vet really. If they did speak to a vet then surely it would have gone down the road of tranquillising.”
Beau Lucy was returned to Rob’s farm, located between the border between Surrey and Middlesex, on Saturday morning with bruises.
He said: “She’s a lot better. Time will tell because we don’t know what internal injuries she might have.”
Beau Lucy is “sulking a bit” and “limping” and she is also on antibiotics and painkillers.
