Rocker Gary Glitter, best known for "Rock & Roll (Part 2)," was found guilty and sentenced to 16 years in prison for his sex offenses during the 1970s and 80s.

Glitter, real name Paul Gadd, was sentenced for attempted rape, four counts of indecent assault and one of having sex with a girl under 13, BBC reports.

A jury found the 70-year-old guilty of the crimes on Feb. 5.

Gadd was found guilty of abusing three girls from 1975 to 1980.

At the sentencing, Judge Alistair McCreath said he did not see Gadd had atoned for his crimes. McCreath said it was clear all of his victims were "profoundly affected" by his abuse.

"You did all of them real and lasting damage and you did so for no other reason than to obtain sexual gratification for yourself of a wholly improper kind," McCreath said.

The judge said he was forced to sentence Gadd under old guidelines of when the crimes were committed. McCreath said he was limited to the maximum sentences during a time when the sentencing climate was less severe.

"The offences for which I must pass sentence today took place many years ago at a time when in particular, in respect of one of them, the maximum sentence was considerably lower than that which is now available," he said.

Today, the crime unlawful intercourse of a child under 13 would be equivalent to rape of a child.

He attacked two girls aged 12 and 13 after inviting them backstage to his dressing room. His youngest victim was 10 years old, and he tried to rape her in 1975.

Gadd had been convicted of child sex abuse in 2006 in Vietnam and sentenced to three years in prison. In 1999, he was convicted of possessing as many as 4,000 images of child abuse and jailed for four months.

Gadd is originally from Marylebone in central London. He denied the allegations against him. The trial lasted only three weeks.
