Platteville police are investigating two incidents where alleged crimes are believed to have been drug-related earlier this week.

A delivery driver told police that a 17-year-old male jumped into the driver’s vehicle and demanded money at Union Street and North Hickory Street Monday around 5:05 a.m.

The driver was able to fight off the subject and get the person out of the vehicle, police said. The driver drove off with the person running after the vehicle.

Police said the male “exhibited violent outbursts” and “repeated irrational/nonsensical statements and appeared to be under the influence of some sort of drug.” The male was taken to Southwest Health Center.

Police then went to the 100 block of Washington Street Tuesday around 12:50 a.m. after a report of an upstairs-apartment resident shouting and screaming and throwing around items in his apartment.

Police arrived to find a broken window, ceiling tiles and damaged items in the apartment. The resident, a 22-year-old man, was “making irrational nonsensical statements and shouting,” and “exhibiting violent behavior,” police said.

The man was taken by Platteville EMS to Southwest Health Center.

In both cases, police said the men are suspected to have taken a controlled substance.

The investigations are continuing, police said.
