Plants costing up to £100 have been stolen in seven separate ‘calculated’ thefts from town centre flower pots.
The arrangements, which are planted by volunteers from Towcester Evening Women’s Institute, have been disturbed over the last 10 days with specific plants removed.
Sue Hamilton, from the institute, said she is ‘very disappointed’ that the expensive collections are being taken from large planters which ‘make a statement’ in Towcester town centre.
She said: “These thefts are not random pranks but are calculated and executed in a very careful manner. The most expensive plants are targeted and are removed with care.
“Not only does it cost more money to replace the plants but it is also upsetting to the WI members who volunteer and give up their time to do all the hard work to maintain these floral planters.
“We’re a bit despondent but I’ve had to tell the volunteers we can’t let this stop us.”
Volunteers have replaced the plants as soon as possible but are now forced to use cheaper versions in case the spate continues.
Mrs Hamilton said: “There are new ones instead but they don’t have the same impact.
“You need something tall for the centre, something to catch the eye, to make a statement but we can’t do that anymore.”
A spokesman from Northants Police said investigations are taking place to establish what exactly was taken and from where.
She said: “Officers would like to speak to anyone who may have witnessed any plants being stolen in the town in the last couple of weeks. Witnesses or anyone with information about this incident are asked to contact police on 101 or Crimestoppers anonymously on 0800 555 111.”
