A wolf who went on the loose in Essex after escaping from Colchester Zoo has been spotted near the zoo, police have confirmed.

The animal was reported missing at 8am this morning, The Essex County Standard has reported.

A police helicopter is assisting a team currently searching for the animal in fields near the zoo. Essex police have since reported a positive sighting of the animal near the enclosure and the area is being contained.

Colchester Zoo said they were "devastated" by the loss of two other Timber wolves who were shot when five of the animals escaped from their enclosure.

They said: "At 7.30am on Tuesday 26 November, it was discovered that the perimeter fence to Colchester Zoo’s wolf enclosure had been damaged and five of the six timber wolves had left the enclosure.

“One of the wolves returned immediately of its own accord and one was darted and recaptured. Unfortunately, as they were further away and an anaesthetic dart takes 15 minutes to take effect, two had to be shot."

The remaining wolf is believed to be sheltering in thick undergrowth.

In a statement, police said: “Police are assisting staff at Colchester Zoo in the search for a wolf which escaped.

“The helicopter and ground units are searching Maldon Road and the fields surrounding.

“Officials at the zoo said Wolves are naturally timid but should not be cornered in any way.”
