Krawetz was working in uniform at the Twin River gambling parlor just north of Providence on May 31 when he escorted out a woman in handcuffs after other patrons complained about her unruly behavior, said Rhode Island State Police spokesman Capt. David Neill.
A videotape shows Krawetz kicking the woman in the side of the head after she apparently tried to kick him, said Michael Healey, a spokesman for the attorney general's office.
Healey said the alleged assault occurred as the woman was cuffed with her hands behind her back waiting on a curb for a patrol car to take her to the police station for booking.
The woman, whose name has not been released, later pleaded no contest to disorderly conduct and has no memory of what happened that night, Healey said.
A Providence County grand jury indictment handed up Friday charges Krawetz with assault with a dangerous weapon.
A telephone listing for Krawetz could not immediately be found and it was not immediately known if he has an attorney. Gary Gentile, a Rhode Island lawyer for the International Brotherhood of Police Officers, declined to comment Friday on the allegations or about whether he would be representing Krawetz.
Krawetz, who has been a Lincoln police officer for 12 1/2 years, is scheduled to be arraigned Jan. 6 in Providence Superior Court.
A spokeswoman for Twin River referred all questions to the police department.
Krawetz is the second Rhode Island officer to be charged in an alleged beating in the past two weeks.
A Woonsocket police officer was indicted last week on civil rights abuses for allegedly beating a 16-year-old boy and urging fellow officers to lie about it to the FBI. The FBI is investigating a separate alleged beating by Providence police officers.
