Stamford in Bloom planters were stolen within a day of volunteers putting them on display
Planters were stolen from Stamford town centre within a day of being put on show.
Eight volunteers were involved in setting up the display in Stamford Walk on Sunday afternoon.
Within 24 hours the two smallest planters had been snatched and the biggest one was taken two days later.
Stamford in Bloom volunteers are devastated that once again their hard work has gone to waste.
There has been a string of incidents during the past12 months with planters getting smashed and plants pulled up.
Volunteer Ann Ellis said the risk of theft or vandalism has become a major factor when the committee considers new projects.
She said: "It's unbelievable. We even joked about whether the planters would still be there the following day while we were installing them.
"Sadly it's something we now have to think about. Usually the planters are secured to the ground, but we knew we were doing this at risk.
“It has both saddened and angered our volunteers that their hard work has been undermined in this way. In addition to people’s time, installing the pots was expensive. Our group has limited funds and incidents like this really set us back”
The two smallest pots were taken on Sunday between 3 and 5pm. The largest bamboo planter went missing on Tuesday and would have needed a vehicle to take it away.
Insp Gary Stewart of Stamford police said: "This is a disgraceful crime. People have taken time and effort to make the town look nicer by creating these displays."
Witnesses should contact Sgt Steve Davidson by phoning Lincolnshire Police on 101.
