The daughter of slain civil rights activist Malcolm X has announced she will sue the New York Police Department and other agencies over his 1965 murder, reports "BBC".

Ilyasa Shabazz says US officials fraudulently hid evidence that they "conspired and carried out their plan to kill" her father.

She announced the planned legal action at the site where he was fatally shot in New York exactly 58 years ago.

The FBI and CIA are also named in the legal filing, her attorney said.

Shabazz, 60, was two years old when she saw her father shot. Three gunmen shot him over 20 times as he prepared to speak in an auditorium in Harlem.

"For years, our family has fought for the truth to come out about his murder," she said at the site, which has since been turned into a memorial.

Malcolm X was the main spokesman for the Nation of Islam – which advocated separatism for black Americans – before his split from the organization. He was 39 years old when he was killed.

A man, a member of the Nation of Islam, confessed to killing him.

In 2021, two other men convicted of murder had their convictions thrown out after a New York judge said there was an error in the verdict.

The two men were later acquitted after the New York attorney general revealed that prosecutors withheld evidence that would likely have exonerated them of the murder. The families of the wrongly convicted men sued and won $26 million from New York and $10 million from New York State.
