A callous thief was caught on CCTV breaking into a primary school to steal hundreds of cartons of milk.
Kincraig Primary School in Blackpool, Lancashire, has been left hundreds of pounds out of pocket after nearly 1,000 cartons of milk were stolen in four months.
Exasperated headteacher Karen Appleby said a total of 200 litres of milk was taken, which should have been enjoyed by children aged 4 to 11.
The school has now released incriminating CCTV footage in a bid to get the perpetrator identified and apprehended.
One clip appears to show a hooded figure accompanied by a small dog jumping over the fence and walking off with some milk.
Another video, dated June 18, shows someone waiting at the gate for the suspect to return from the school grounds and hand over the haul.
Milk gets delivered to Kincraig Primary School by delivery men with their own key every day between midnight and 2am.

Teachers first noticed cartons were missing in June and they say the thieving continued "on and off" until the end of the summer term.
However, since September the culprit has been helping himself every single day and on Thursday last week he took 120 cartons at once.
Mrs Appleby said: "He jumps over the railings with his little dog following him and helps himself to as much milk as he wants.
"He comes at different times so somebody would have to sleep outside to catch him in the act, and we can’t do that.
"Unfortunately for us he has always got his hood up and you can’t see his face."
Mrs Appleby said teachers had taken to using their own cash to replace the milk, which is given to pupils free of charge as part of a balanced diet.
"We don’t want them to go without it," she said.
"It’s not so bad when it’s just one sleeve because there’s always some days when children don’t want milk, but since September we have had to go out and buy quite a lot of milk."
She added: "We get discretionary food parcels here at the school, and if anyone walked off the street and said they had no money and no food we would never turn them away, and if he was desperate enough to take just a couple of cartons of milk I could understand.
"But when it’s 120 of them in one night it comes to a bit more than desperation."
The school appealed to parents for information about the mystery milk thief this week.
