Jim Davidson, 59, answered bail today after being held in January by detectives working on Operation Yewtree, the investigation prompted by the Jimmy Savile sex abuse scandal.
A Scotland Yard spokesman said a 59-year-old man had been "further arrested on suspicion of sexual offences in connection with further allegations made to Operation Yewtree".
At the time of his first arrest in January, Davidson's solicitor Henri Brandman issued a statement to say he "vigorously denied" the allegations.
