Colchester Zoo said it was "devastated" by the death of two of their "beloved" Timber wolves.
The two wolves were among five that escaped their enclosure this morning at around 7.30pm. In a statement, the Zoo said they were still looking for one of the escaped wolves, with the help of police.
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 thought to be sheltering in thick undergrowth and the police are assisting in its recapture. Wolves are naturally timid and provided they are not cornered in any way do not provide a risk to the public.
