British police said there was insufficient evidence to prosecute comedian Freddie Starr as part of an investigation into allegations that followed revelations the late BBC presenter Jimmy Savile sexually abused hundreds of children.
The 71-year old comedian, singer and impressionist was arrested in relation to allegations of sexual offences made by 13 individuals in December 2012.
"We have concluded that the available evidence does not offer a realistic prospect of conviction for any of the alleged offences," said Chief Crown Prosecutor Baljit Ubhey.
Police began their investigation, named Operation Yewtree, after it emerged following Savile's death in 2011 that the TV presenter had committed sex crimes on an unprecedented scale over six decades.
Britain's best-known celebrity publicist Max Clifford was jailed for eight years last week.
It came after he was convicted of indecently assaulting teenage girls in the 1970s and 1980s.
He is the first person to be found guilty since the inquiry was set up.
