UMPD is investigating related incidents that occurred Thursday and Saturday mornings involving “bottle bombs” that were likely thrown from a building. These devices are fabricated using materials that create a chemical reaction causing the bottle to swell and explode which can cause injuries and severe chemical burns. Please be aware that even bottles sitting for a while still have the potential to explode due to an unpredictable chemical reaction. 

We ask that people remain cautious and examine any discarded bottle carefully from a distance. If the bottle shows signs of swelling or melting, call (413) 545-3111 or 911 and stay clear.
