Gary Glitter, a former British pop star, was sentenced to 16 years in prison on Friday. Feb. 27, 2015.

The 70-year-old former glam rocker, whose real name is Paul Gadd, was convicted on six charges of sex offenses involving teenage girls, some as young as 12 years old. Glitter previously spent two months in a British jail for possession of child pornography after a 1999 conviction.

The sex offenses occurred between 1977 and 1980. The "Rock and Roll" singer is accused of four counts of indecent assault involving the first complainant, who was aged 12 or 13 at the time, between January 31 and May 31, 1977.

Glitter was arrested in Oct. 2012 as part of the national investigation called Operation Yewtree, which was launched after a child abuse scandal involving Jimmy Savile, the late BBC entertainer. Glitter was the first person arrested as part of the Operation Yewtree investigation launched in the wake of the Jimmy Savile child abuse scandal.

Other suspects in the Yewtree  probe are currently on bail. Former Radio 1 DJ Chris Denning was charged with 41 offences last month. The charges included 34 counts of indecent assault. The allegations dated from between 1967 and 1985.

Glitter is best known for his 1970s hit "Rock and Roll (Part 2)." He was convicted on child abuse charges in Vietnam.

Glitter was first questioned about the sex charges in October 2012 after he was arrested at his home in Marylebone, central London.Glitter was held at his home in October 2012 and was later released on bail. Bail had been March this year. His bail is pending further enquiries.

Glitter was accused of one count of "administering a drug or other thing in order to facilitate sexual intercourse." The Crown Prosecution Service issued a statement saying the first victim, who was 12 or 13 years old at the time, claimed that Glitter had sex with her, indecently assaulted her and drugged her for sex in 1977.

The second girl, who was 13 or 14 at the time, claims that Glitter indecently assaulted her between late 1979 and the end of 1980.

Comedian Jimmy Tarbuck spent nearly a year on bail before being told he would not face charge after he was arrested. The comic Jim Davidson was also part of the investigation but also faces no further action.

Mike Osman, a DJ, and Wilfred De'Ath and Ted Beston, former producers at BBC, were also arrested and later told they would not be charged. Radio 1 DJ Dave Lee Travis was cleared of charges of 12 sex attacks by a jury but still faces three charges.
