OAK BLUFFS, Mass. -- Harvard scholar Henry Louis Gates Jr. is accusing a Cambridge Police officer of lying and fabricating a police report that detailed Gates' arrest on disorderly conduct charges.

"I think he owes me an apology for what he did," Gates told NewsCenter 5's Liz Brunner in an interview Tuesday night. "He should look into his heart and know that he is not telling the truth and he should beg my forgiveness."

Gates was arrested after what the report described as a tumultuous and frightening confrontation with police last week.

Police had been called to Gates' Cambridge home after a passerby saw two men trying to get into the house. According to the report, a woman said she saw a man "wedging his shoulder into the front door as if to pry the door open."

Gates, 58, who had just returned from a trip to China was attempting to open a door that was broken.

Sgt. James Crowley said when he arrived to question him, Gates called him a racist and told him "you don't know who you are messing with."

"I said 'What is this about? I want your name and your badge number'," Gates said.

"He wouldn't answer me and he just stood and stared at me. I said, 'Are you doing this because I am a black man in America? Are you doing this because you're a white police officer and I am a black man?'"

According to the police report, Crowley repeatedly tried to answer Gates, but was interrupted when Gates started yelling at him and making threats.

"I was recovering from a bronchial infection which I contracted in China. It's impossible for me to yell even now," Gates said.

But Gates -- one of the nation's pre-eminent black scholars and the director of Harvard University's W.E.B. DuBois Institute for African and African American Research -- admitted that he was adamant in demanding the officer's name, since he intended to file a complaint against him.

"You can not presume that someone is guilty simply because they are black, sitting at home, and that's what was wrong with this situation," he said.

Gates most explosive charge is that Crowley then lured him onto the front porch in order to arrest him.

"You are constitutionally protected (from arrest) without a warrant in your own home," said Gates, who followed the officer out of the house in order to get his name and badge number.

"I regret stepping out on that porch! To my amazement, all these police officers had shown up."

"I asked the officer there, 'Would you give me this man's name and badge number?'" Gates said. "Sgt. Crowley, tapped me on the shoulder and said, 'Thank you for accommodating my earlier request. You are under arrest.' And he slapped handcuffs on my behind my back."

Cambridge police dropped the charges against Gates Tuesday calling the incident "regrettable and unfortunate." However, spokeswoman Kelly Downes said both Gates and Crowley had acted badly.

Gates said he is still considering filing a complaint, but wants an apology from Crowley.

"This has just to do with human relations between a man who did something terribly wrong and then lied about it," Gates said.

"The idea that I would be arrested in my own home for demanding a police officer's name and badge number is fundamentally astonishing."

Cambridge police said they considered the matter closed and declined requests for further comment.
