A large number of weights have been stolen from a fitness centre in Crick.
Burglars broke into the building in Yelvertoft Road sometime between 9.30pm on September 3 and 6am today (Friday September 4).
After smashing open the front door, the thieves took a large number of coloured weights, sets of boxing gloves and pads and a generator.
The weights were similar to those pictured and one of the sets of gloves was a distinctive Max Pro make in red white and blue.
