The arrest took place at 12:44 p.m. ET on Wednesday in Gwinnett County, Ga., just north of Atlanta. Jennings was released at 3:41 p.m. ET.
Jennings just completed his fifth season in Chicago. The 31-year-old has started all 32 games over the last two seasons and earned Pro-Bowl nods in 2012 and 2013.
The Bears released a statement on the matter on Wednesday afternoon:
"We are aware of the reports regarding Tim Jennings' arrest," the statement reads. "We are currently gathering information to learn more about the circumstances surrounding the situation."
Prior to joining the Bears, Jennings spent four seasons with the Indianapolis Colts, who selected him in the second round of the 2006 draft out of Georgia.
Over 16 games in 2014, Jennings recorded 50 tackles and seven passes defended as the Bears posted a 5-11 record and finished in last place in the NFC North.
