Zombies roamed the corridors of Mill Hill School chasing students to raise money for a cancer charity.
The zombie apocalypse raised more than £300 for Macmillan Cancer Research, making it the single most successful charity event to be organised by students at the Ripley school.
Sixth formers came up with the innovative idea, which saw about 30 of them dress up as zombies and chase more than 120 students through the school.
Those taking part had to solve riddles to move from room to room and they wore a tag which the zombies had to grab.
The event was held as part of Rag Week, during which a host of activities are organised by students to raise money for charity.
So far, the overall total for the week stands at more than £500 and includes money raised from the zombie apocalypse, raffles and cake sales.
Student Amy Reeve, 16, of Ripley, said the zombie apocalypse proved to be much more successful than they had anticipated.
She said: “We were trying to think of something original and we do sit around and sometimes think about what we would do if there was a zombie apocalypse so we thought we could try to re-create one.
“We used the tag rugby belts and the zombies had to try to get the tag. Anyone who was playing and was caught could pay £2 for another tag and get back into the game. We were really pleased with the amount raised and it’s definitely something we would like to do again.”
Students also organised a ‘survival room’ in which those taking part in the after-school event, which was supervised by teachers, could buy sweets and drinks.
Steve Richardson, Director of Learning for Years 12 and 13 at Mill Hill, said the event was a massive success.
He said: “It was fantastic and has become the single most successful fund-raising activity to be organised by students. It was really well organised and even the rain didn’t put anyone off.”
