Hopkins police want help with an investigation into dog poisonings that involve dumping antifreeze and poison in yards of people who own dogs.

The police issued a one-page statement saying they wanted to “make the community aware of incidents” of dog poisoning in the 200-300 blocks of 9th and 10th avenues N.

Someone purportedly is placing antifreeze in dog food and “blocks of poison” in the yards of unwitting dogs and their owners.

Police did not say what type of poison was being placed in the yards nor did they say whether any dogs have died or been injured as a result of poison consumption.

A $1,000 reward is being offered for information leading to the arrest and conviction of those responsible. Hopkins police suggest using the Tip 411 app to send an anonymous text, photo or video. Tipsters can also call 952-938-8885 and ask for Investigator Denny during regular business hours.

Poison ingestion can be deadly to dogs and their owners.
