Harris is one of 12 people who were arrested in Operation Yewtree, which was created following Savile's 2011 death when hundreds of allegations were made against the former BBC DJ and TV personality, the BBC reported Friday.
Harris was first questioned in the case against Savile in November, the report said.
He was then arrested on March 28.
At that time, Scotland Yard said: "An 82-year-old man from Berkshire was arrested by officers on Operation Yewtree on suspicion of sexual offenses.
"He has been bailed to a date in May pending further inquiries. The individual falls under the strand of the investigation we have termed 'others.'"
Harris has not yet commented on his arrest.
Other high-profile people who have been questioned in the Savile case include public relations consultant Max Clifford, comedian Freddie Starr, DJ Dave Lee Travis and comedian Jim Davidson, all of whom have denied any wrongdoing, the BBC said.
David Smith, 66, a former driver for the BBC, was arrested in December and was charged with past sex offenses in the case.
