A group of heartless youths "ripped up" hand-knitted snowmen and penguins when they targeted a Christmas display in Brook Street.
The display, which represented charities including The Hospice of St Francis, was badly damaged by the vandals at around 5pm on Sunday (December 15).
One resident said: "I can never express how grateful I am to all those amazing people who make these things [knitted displays].
"It's just so sad a tiny amount of people want to ruin it for the rest."
Others angrily took to social media to condemn the senseless act of vandalism.
"All the work we put in and someone has to spoil it for other people. Why," one typed.
Another added: "So sad. Went into Tring and it looked truly amazing, such hard work people spent making the town look magical.
"And then someone comes along and ruins hours of work. So selfish."
Police investigating the incident of criminal damage are now appealing for the public's help.
A spokesman said: "Any witnesses or anyone with information should call the non-emergency number 101 quoting crime reference 41/112533/19."
