Rolf Harris was arrested again on suspicion of new offenses.
Rolf Harris, 83, was questioned over “further allegations” made to detectives at Scotland Yard’s Operation Yewtree.
They arose after he was first revealed to be a suspect in the controversial inquiry four months ago.
The British police refused to discuss the nature of the allegations. But they are now believed to involve more than one complainant and cover a period of several years.
Police insisted that the allegations remain unconnected to Jimmy Savile, who sparked the Yewtree inquiry.
Neighbors said Rolf Harris has not been seen at his home in Bray, Berkshire, for several days.
The Australian-born star is the biggest name to be arrested as part of the inquiry.
It is understood that he vehemently denies the allegations but has declined to issue a formal statement on the matter.
Rolf Harris’s wife of 55 years is the Welsh sculptress and jeweller Alwen Hughes, 81.
The artist and singer received a rapturous reception from fans when he performed on London’s South Bank and in Bristol this year.
Others held as part of Operation Yewtree include pop star Gary Glitter, comedian Freddie Starr, DJ Dave Lee Travis, publicist Max Clifford and comedian Jim Davidson.
