Up to 20 rhea birds have been giving police the run around after they were spotted charging through housing estates and near the M25.

Hertfordshire Constabulary says the birds, which look like a small ostriches, have been running wild in the Maple Cross area and alongside the motorway.

A police spokeswoman confirmed local officers believe there could be up to 20.

They have carried out enquiries to identify the owner of the birds but have concluded that they are wild.

The force is now working with Three Rivers District Council to “come up with a plan” to capture and rehome the birds.

In the meantime, people are being warned not to appraoch the animals as they can be "aggressive if cornered".

PC Christian Gottmann, from the Rickmansworth and District Safer Neighbourhood Team, said the force has received reports of them attacking dogs and deer.

“So we ask that dog owners are vigilant when out walking,” he said.

He added: “These birds are certainly an unusual sight on the streets of Three Rivers, and we want to reassure the public that we are working in partnership Three Rivers District Council, Highways and our Rural Operational Support Team to come up with a plan to capture and rehome the birds to a suitable animal reserve.

“Enquiries are ongoing but if you think you may be able to help with this, please get in touch with us. In the meantime, we would advise the public not to approach these animals as they are very fast, much like their larger counterparts, and can be aggressive if cornered.”
