More details via the World-Herald:
Lincoln police Capt. Jason Stille said Dennard, 24, was pulled over and then cited about 2 a.m. Thursday near 50th Street and Normal Boulevard. He said Dennard, who was westbound on Normal in some type of a Honda, was spotted by officers straddling a lane line between 50th and 56th Streets.
Later, Dennard was arrested on suspicion of DUI, refusing a chemical test and a driving infraction. He said Dennard was alone in the vehicle when he was pulled over.
This isn't Dennard's first run-in with authorities. In April 2012, a week before the draft, he was arrested and charged with assaulting a police officer in Lincoln. The Patriots still drafted him in the seventh round out of Nebraska. This February, Dennard was convicted of assaulting the officer and, two months later, was sentenced to two years' probation, 30 days in jail and 100 hours of community service. That sentence is expected to start in March 2014.
The team issued this statement on Thursday morning: "The New England Patriots are extremely disappointed to learn of Alfonzo Dennard's arrest. We take this matter very seriously and are working to get more information on the incident."
As a rookie, Dennard started seven games and registered 35 tackles, three interceptions and seven passes defended.
Dennard's latest arrest could be considered a violation of his probation. He could also face disciplinary action from the Patriots and the NFL.
