The Minnesota State Patrol says alcohol was involved in two separate weekend incidents where a trooper squad was struck in the Twin Cities. 

According to the patrol, the first incident occurred late Friday evening on Interstate 94 near Franklin Avenue in Minneapolis. There, a driver in a Toyota Camry struck an unoccupied squad car of a trooper who was at the scene of a prior crash. 

The driver, a 24-year-old St. Paul man, was arrested on suspicion of driving while intoxicated and criminal vehicular operation.

One of his passengers "suffered non-life threatening injuries" in the crash, the state patrol said. It's unclear if the trooper was hurt. The crash is still under investigation. 

The second incident occurred late Saturday evening on Interstate 35W at Highway 96 in Arden Hills. 

A trooper was in the area due to a driving complaint concerning a driver of a white Lexus, officials said. The motorist was traveling south on the interstate when they struck another motorist and then the trooper's squad vehicle, disabling all three vehicles. 

Officials say the driver of the white Lexus, a 39-year-old man, drank alcohol before the crash, but was below the legal limit and passed the field sobriety test. He was issued a citation for reckless driving. All drivers were evaluated by medics at the scene, but did not require hospitalization.
