DJ Dave Lee Travis has been taken "off air with immediate effect" by radio station Magic AM after his arrest yesterday.
Travis, who was arrested by officers investigating the Jimmy Savile abuse scandal, presents a weekend show on the station.
A spokeswoman for Bauer Media which owns Magic AM said:
"Following the arrest and release on police bail of Dave Lee Travis, Bauer Media has decided to take him off air with immediate effect from his Magic AM weekend shows, which broadcast across the north of England.
"We understand that the allegations about which he was questioned by police pre-date his time as a freelance contributor to Magic AM.
"While we can make no judgment on the matters under investigation, we believe it would be inappropriate for him to broadcast until they are resolved."
The former Radio 1 star, from Leighton Buzzard, Bedfordshire, was held at 7.45am yesterday on suspicion of sexual offences and bailed later to return on a date in early January.
