In a statement the zoo said: “Since confirming that we had new photographic evidence of Samba’s whereabouts in August, our team has continued working tirelessly to bring her safely back to Marwell Zoo.
“Recovering Samba is a gradual and carefully managed process. Although we know the area she is in, it isn’t simply a case of being able to approach and collect her.
“It’s vital that we keep any stress to an absolute minimum, as frightening or disturbing her could cause her to move away from the area and make her safe recovery more difficult.
“Over recent weeks, we have installed additional wildlife cameras, which have provided further photographic evidence of Samba.”
