Former BBC radio DJ Dave Lee Travis was arrested by police as part of an investigation into alleged child abuse centering on former BBC presenter Jimmy Savile.
Police said Mr Travis, who in 67-years-old, was arrested this morning on suspicion of sexual offences and taken into custody.
He was bailed pending further inquires to return in early January, police said.
Mr Travis returned home at 9.15pm in the passenger seat of a silver car.
He stared straight ahead as the vehicle was mobbed by photographers.
Three police officers stood nearby as the car drove slowly through the gates.
An officer told reporters that Travis would not be making any comment tonight.
450 victims have so far come forward and that police had recorded 200 allegations of sexual assault.
It is the fourth arrest in the operation police have codenamed "Yewtree".
Police are dividing their investigation into three strands: offences allegedly committed alone by Savile, offences committed by him with others, and offences committed by others alone.
A police statement said today's arrest fell into the third category.
The allegations of abuse have shaken Britain's state-funded broadcaster and shocked fans of Savile, who died last year at the age of 84.
