It added: “We’ve received many possible sightings, but without photos or video, it has been difficult to confirm whether these reports are Samba or muntjac deer which can look very similar.”
Five days after her escape, Samba was seen resting in the sunshine at the side of a river near the zoo by a dog walker who captured phone footage as she jumped in the water and swam off.
Samba and her sister, Tango, arrived at the zoo on 16 March after being transferred from Suffolk, but both escaped the following day.
Tango was found close to the pair’s temporary enclosure at the zoo and was swiftly retrieved but her sibling – described as the “more adventurous” of the pair – has been at large ever since.
Marwell Wildlife added that Tango “has been enjoying the warmer weather, often seen relaxing in the sun and napping in her hay”.
