Police said Davis is a suspect in a domestic violence assault that occurred on June 3 in the Adams Morgan neighborhood.
Davis was suspended indefinitely by the NFL in February 2014 for violating the league's substance abuse policy. He had previously been suspended four games for failing a drug test in 2011.
The day after Davis was suspended indefinitely, he was arrested and charged with DUI. Davis pled not guilty, and the case was dismissed after the judge ruled police did not have sufficient cause to initiate the stop.
Davis has played six seasons in the NFL, all with Washington. He was a second-round pick out of USC in the 2008 NFL draft.
