An attorney representing the family of a 7-year-old Detroit, Michigan, girl killed in a police raid filed lawsuits in state and federal courts Tuesday, accusing the police of a cover-up.

"This type of activity by a police force is unacceptable in America," said Michigan attorney Geoffrey Fieger at a news conference in his office. "What is equally unacceptable is the cover-up that has occurred."

Fieger said the lawsuits allege gross negligence, a violation of civil rights and a conspiracy to cover up the violation of civil rights.

Aiyana Jones died early Sunday after she was hit by gunfire during a police raid at her home.

Detroit Assistant Police Chief Ralph Godbee has said that police were executing a search warrant for a suspect in a shooting two days earlier that killed a high school student.

He said preliminary information indicated that members of the Detroit Police Special Response Team approached the house and announced themselves as police.
