Sheds at the allotment site in Biggleswade were broken into on the evenings or overnight on June 10, 17 and 22.
Padlocks were broken off the sheds to gain access, leaving plot holders to repair the damage caused.
It seems whoever did this was looking for specific items, as many of the sheds appear to have had nothing taken.
Biggleswade Town Council who run the allotment site have been informed, along with the Police.
If anyone has had damage to their shed they are advised to phone the Police on their non-emergency number 101.
