Singer Cliff Richard says he is pleased with prosecutors' decision to drop an investigation into historical sexual abuse.

He said in a statement Thursday he is "obviously thrilled that the vile accusations and the resulting investigation have finally been brought to a close."

The Crown Prosecution Service says there is insufficient evidence to prosecute and South Yorkshire Police have apologized for the handling of the case.

The 75-year-old singer said he had cooperated fully with the nearly two-year investigation.

He was questioned by detectives in 2014 but wasn't arrested or charged.

Richard has remained a popular act in Britain following his heyday in the late 1950s and early 1960s, just before the Beatles burst onto the music scene.
