Police investigating child-sex abuse allegations against the late BBC TV host Jimmy Savile arrested former glam rock star and convicted sex offender Gary Glitter Sunday, British media reported, raising further questions about whether Savile was at the center of a broader pedophile ring.

Police would not directly identify the suspect arrested Sunday, but media including the BBC and Press Association reported he was the 68-year-old Glitter.

The musician, whose real name is Paul Gadd, made it big with the crowd-pleasing hit "Rock & Roll (Part 2)," a mostly instrumental anthem that has been a staple at American sporting events, thanks to its catchy "hey" chorus. But he fell into disgrace after being convicted on child abuse charges in Vietnam.

Sunday's arrest was the first in a widening scandal over Savile's alleged sex crimes, which started gaining attention earlier this month when a TV documentary showed several women claiming that Savile abused them when they were teenagers.

Hundreds of potential victims have since come forward to report similar claims to police against Savile, who died last year at age 84.

One witness recently told a BBC TV show that she once saw Glitter having sex with a schoolgirl in Savile's dressing room at the broadcaster's TV center in the 1970s.

Glitter has denied the allegations.

Police have said that though the majority of cases they are investigating relate to Savile alone, some involve Savile and unidentified suspects.

The scandal has raised questions about whether the BBC, the publicly funded broadcaster, had ignored crimes it suspected over several decades.

BBC executives have apologized and vowed to uncover the true scale of the alleged abuse.

"The BBC's reputation is on the line," Chris Patten, chairman of the BBC Trust, wrote in The Mail on Sunday newspaper.
