According to Baltimore County police, Smith was trying to help an intoxicated woman in the bathroom of a Towson, Maryland, bar when she became nauseated. Medics arrived, and officers asked Smith multiple times to move away from the scene. Smith refused and began to argue with officers.
Smith is the fifth Ravens player to be arrested this offseason, after running back Ray Rice, offensive lineman Jah Reid, wide receiver Deonte Thompson and rookie running back Lorenzo Taliaferro.
Smith, 25, was a first-round pick by the Ravens in 2011. He had 58 total tackles and two interceptions last season.
Smith is set to make a $1.392 million base salary this year and $6.898 million in 2015 after the team exercised a fifth-year option in his contract.
