Freddie Starr's lawyers have said they are "astonished" at the length of time a police investigation into alleged sexual offences is taking.
The 70-year-old has been rebailed until early December after his initial arrest in November last year by officers from Operation Yewtree, the national investigation sparked by abuse allegations against Jimmy Savile.
His lawyer Dean Dunham released a statement to say: "Freddie was due to return to the police station today to answer bail and our belief was that this would have marked the end of this matter.
"However, we have been informed that the police have instead re-bailed him to 5th December. We are astonished at the amount of time this investigation is taking in relation to Freddie and indeed surprised, on the basis of what has been put to him, that he even remains under investigation."
Starr's first arrest was over claims involving Savile and others, and he was re-arrested in April this year over additional allegations that did not involve the late DJ.
The comedian has denied any wrongdoing.
A Scotland Yard spokesman said: "We are doing all we can to conclude matters as quickly as possible but it should be appreciated that the delays are the result of the complex nature of these inquiries."
