Collins,well known for playing a wholesome pastor in TV series "7th Heaven," has been fired from a sequel to satirical movie "Ted" following the revelation by celebrity news website TMZ, media reports said.
In the audio tape obtained by TMZ, the 67-year-old actor appears to admit during a 2012 therapy session to inappropriate behaviour with at least three under-age girls.
"There was one moment of touching where her hand ... I put her hand on my penis," he is heard to say, referring to an 11-year-old girl.
A spokesman for the LA Police Department (LAPD) said officers were reviewing an investigation into a criminal complaint filed at the time.
Collins' estranged wife, actress Faye Grant, allegedly taped the therapy session in 2012 and also discusses the alleged molestation in 2014 divorce documents.
