LOS ANGELES — Two cable television networks said Tuesday they would not broadcast scheduled re-runs of veteran TV actor Stephen Collins’ beloved family series “7th Heaven.”

The networks, UP TV and TV Guide, announced the cancellations after details of molestation allegations against Collins were reported by celebrity website TMZ.

New York police confirmed Tuesday they have an open investigation into allegations the actor molested a teenage girl in the early 1970s.

New York Police Department spokesman Stephen David said the complaint was filed in 2012 accusing Collins of forcing a then-14-year-old girl to commit a lewd act in the actor’s Manhattan apartment in 1972. David says the case remains open and is being handled by Special Victims Division detectives, but no charges have been filed.

Prosecutors will make a determination about whether any charges should be pursued.

Collins’ lawyer, Mark Vincent Kaplan, and talent agent, Mark Teitelbaum, did not return messages seeking comment Tuesday.

Hollywood trade publications reported Tuesday that Collins lost a role in the film “Ted 2” and resigned his position from the acting guild SAG-AFTRA.

Pamela Greenwalt, a spokeswoman for SAG-AFTRA, declined comment on Collins’ departure from its national board. The actor’s name had been removed from lists of current board membership by Tuesday afternoon.
