The caption underneath the image reads "Undercover #420 operations are in place". Also pictured were a police vehicle and officer standing by with a net.
The "traps" are Doritos, Cheetos, Mountain Dew, White Castle and video games such as "Grand Theft Auto". "Discreet traps have been set up throughout the city today".
Since the tweet was sent at about 5 a.m. Thursday, it has been retweeted over 60,000 times and climbing.
Police in Wyoming, Minnesota are once again having fun with tweets on 4/20 - the well-known nationwide "holiday" for marijuana users.
Here is a picture of their tweet from previous year on April 20th.
The Wyoming Police later tweeted that it is attempting to use humor to bring attention to substance abuse issues.
The Wyoming Police Department's 4/20 tweet from past year featuring a cardboard box "trap" with Cheetos and Doritos also went viral. They also offered to help find resources to those with substance abuse issues without issuing jail time.
