University police arrested the boyfriend of a University of Minnesota student at Pioneer Hall for fifth-degree domestic assault Friday evening. A University police department report stated that Christopher Stowers, 18, was arrested after his girlfriend, 18, alleged he had put her in a headlock and threatened her. The officers did not see any visible marks on the victim, according to the report. While these were only allegations, an arrest needed to be made according to UMPD policy, University police Deputy Chief Chuck Miner said. âÄúBasically, police officers donâÄôt have a lot of discretion when it comes to domestic assault cases,âÄù Miner said. âÄúGenerally, if thereâÄôs evidence of a domestic assault, officers are required to arrest the person who is responsible.âÄù Miner said that when cases of this sort occur, itâÄôs fairly common to see an arrest result, regardless of whether the victim decides to press charges. He said the state of Minnesota has a policy that requires the arrest of the party responsible for the assault. Stowers was taken to Hennepin County Jail. He posted bail and was released Saturday. Gun found after traffic stop in Southeast Como A Minneapolis man was arrested for carrying a weapon without a permit and driving without a license Saturday night. Delano Willett, 39, was pulled over near the intersection of 20th and Como avenues southeast, almost a mile from his home, according to a Minneapolis police report. On his driving record, WillettâÄôs status is cancelled and denied indefinitely as âÄúinimical to public safety,âÄù which was the result of three or more convictions of driving while intoxicated in a 10-year period, according to the report. Minneapolis police Lt. Greg Reinhardt said the officers ran the license plate of WillettâÄôs vehicle and found a warrant for his arrest. As the officers were interviewing Willett, they saw what looked like a handgun in plain view, Reinhardt said. Willett was then placed in custody. The gun was later found to be a BB gun, which in this case was illegal to carry without a permit. âÄúYou certainly canâÄôt be driving around with that in your vehicle,âÄù Reinhardt said of the incident. Willett was taken to Hennepin County Jail. He was released Sunday.
