The lawyer of a D.C. police captain who is suing the department is demanding an FBI (web) investigation into a raid on a property he owns on Georgia Avenue, claiming it was part of a conspiracy with the media to discredit the captain. The lawyer says he will file a $2 billion lawsuit against the city and a media organization, claiming they violated the civil rights of the police captain, and the family who resides in the home.

Many questions still surround the July 31 raid at the home in the 2900 block of Georgia Avenue, NW, which was captured by an ABC 7/NewsChannel 8 camera crew. It's even unclear as to who is responsible for the raid. The Drug Enforcement Agency would not answer any questions Tuesday, referring ABC 7/NewsChannel 8 to D.C. police. The MPD said it can't comment because of pending litigation.

Police initially said they were targeting a drug and gambling ring. But the people inside the home say they were having a birthday party, and that officers didn't find anything, and were abusive.

"They just came in and started hitting people," said the 23-year-old woman who hosted the party. She did not want to be identified.

About 24 people were at the party when the heavily armed officers knocked at the door and announced the raid. The woman says she called her mother, who rents the house from the District's Section 8 housing program.

The mother claimed she could hear officers "swearing and using slurs in the background and the nose of things being broken," according to an affidavit.

No one at the home was arrested or charged. But those present claim police were abusive. They say the officers were focused on the owner of the home, MPD Captain Melvin Gresham, who rents the property to the city's subsidized housing program.

Gresham is already suing the police department for $100,000 after he was accused of asking a junior officer to alter a report on a traffic crash in which Gresham was involved. Gresham is also a witness for a fellow officer who is suing the department for alleged sexual assault and battery.

Gresham's lawyer claims the so-called drug raid -- and an alleged leak to the media implicating Gresham as the owner of the home -- was an attempt to find something to use against Gresham and to tarnish his reputation.

"What we have here, clearly, is an overt attempt, an overzealous attempt, by the police department to carry out the vendetta," said E. Scott Frison Jr.

The woman who rents the home, but was not home at the time, and her daughter, agree with the lawyer's theory.

"I really believe it was about Mr. Melvin Gresham," she said. "They asked me on the telephone who do I rent from, where was Mr. Gresham."

"They threatened to take my baby away if I didn't give up some information about Mr. Gresham," said the daughter.

Police did not respond to a request to comment on the story. Gresham's attorney plans to file the $2 billion lawsuit August 31, unless his client's demands are met. Those include firing all the officers allegedly involved in the planning, executing and authorizing the raid, including police Chief Cathy Lanier (web|news|bio) .
