Up to 20 rhea birds that have been running around a housing estate will be sent to an animal reserve when captured, police said.

The "unusual sight" has been spotted at Maple Cross, close to the M25, Hertfordshire Police said.

The force was working with Three Rivers District Council and highways teams to "come up with a plan".

Police said they had tried to identify owners, but concluded the flightless birds were effectively wild.

The birds have been compared to Road Runner, from the Looney Tunes carton, on social media.

PC Christian Gottmann, from the Rickmansworth and District Safer Neighbourhood Team, said the birds were "an unusual sight on the streets" and that police and Three Rivers District Council were working on a plan to capture and rehome them.

"Inquiries are ongoing, but if you think you may be able to help with this, please get in touch with us," he said.

He advised the public not to approach the "fast" animals as they were "aggressive if cornered".

"Unfortunately we have received reports of them attacking dogs and deer, so we ask that dog owners are vigilant when out walking," he added.

A Hertfordshire Police spokeswoman said the precise number of birds on the loose was unknown, but the local policing team believed it could be up to 20.
