Children at a primary school were forced to evacuate their playground because of an "unusually aggressive" squirrel wreaking havoc.
The grey squirrel had earlier scratched a member of staff at the Chater Infants School in Watford, Hertfordshire, The Watford Observer reports.
Teachers had to escort pupils out of the playground and back into the safety of the school building after the creature then proceeded to "disrupt" playtime.
Headteacher Amrit Bal-Richards said the school is monitoring the situation and its caretaker is being "extra vigilant".
She said: "We did have an incident where we had a squirrel. It is very uncommon for a squirrel to be a little aggressive. It was a little bit tempered. We will be monitoring the situation and the caretaker is being extra vigilant.
"We talked to the children at an assembly the following day to say some times animals can be aggressive and a bit tempered and what to do if that happens."
The incident took place earlier this month and the squirrel has not been seen since. None of the children were injured.
