In the report, police said Rice and his fiancée "struck each other with their hands," but no injuries were reported. Both were released with summons to appear in court, according to police.
"We haven't seen any charging documents yet," Rice's attorney Michael Diamondstein said. "There was an argument that included Ray. I can't give any specifics because we haven't seen the document yet.
"Once we're able to go through the evidence, it should wind up to be little more than a misunderstanding."
A Ravens spokesman said the team spoke with Rice and knows he and his fiancée returned home together after being detained.
"We are aware of the Friday night situation with Ray Rice and his fiancée," the Ravens said in a statement Sunday night. "We have spoken with Ray, and know that they returned home together after being detained."
Rice, 27, signed a five-year, $35 million deal with the Ravens before the 2012 season. He is coming off his worst season with the team, gaining 660 rushing yards and averaging a career-low 3.1 yards per carry.
