An iguana badly injured when it was used as a “weapon” in a bizarre attack cannot get the surgery it needs — because it is under police protective custody, according to the vets trying to treat it.

Copper the Iguana is missing part of its tail and also has a leg fracture after an angry diner swung the animal around his head and then threw it at a restaurant manager in Painesville, Ohio, last month.

The Lake Humane Society is now waiting for permission from the courts to treat Copper, who also has bone disease.

“Copper is under protective custody and the case is being handled by the Painesville Police Department,” the humane society said in a fundraising appeal for the $1,600 the surgery will eventually cost.

“We are awaiting permission to perform the surgery Copper requires as a result of her injuries. Once we receive approval from the courts, we will get Copper the care she needs.”

Arnold Teeter, 49, has been charged with cruelty to animals and disorderly conduct over the attack, according to News 5 Cleveland.

“We need your help to give this innocent reptile a second chance at life,” the humane society said of its fundraising.
