The U.K. Attorney General has declined to appeal disgraced entertainer Rolf Harris' five-year sentence for child sex offences after receiving a slew of complaints suggesting the punishment is not enough.

The Australian singer/artist, 84, was ordered to serve five years and nine months behind bars in June (14), after he was convicted of 12 indecent assault charges regarding the molestation of four young girls between 1968 and 1986, when they were aged from seven to 19.

The punishment, handed down by judge Justice Sweeney, was considered by many to be too lenient and prompted 150 people to file official complaints about the sentence with U.K. authorities.

However, Attorney General Jeremy Wright has decided against challenging the sentence in the Court of Appeals.

A representative for the Attorney General's Office reveals, "He (Wright) did not think they (appeal judges) would find it to be unduly lenient and increase it...

"The sentencing judge was bound by the maximum sentence in force at the time of the offending.

"The judge made some of the sentences consecutive to reach the total sentence, but he could not simply add up sentences on individual counts; the overall sentence had to be just and proportionate to the overall offending."

Harris, who denied the counts, was stripped of his British Academy of Film and Television Arts (BAFTA) fellowship and his Australian Recording Industry Association (Aria) Hall of Fame honour following his conviction.
