“Thankfully a significant amount of Class A drugs was discovered by our officers that could have caused serious casualties and misery in our community.
“Please contact us if you think someone could be using or supplying drugs near where you live so we can continue to take similar action and stop the spread of illegal drugs that could endanger our officers and others in your area.”
