The pro-reproductive health group Planned Parenthood is already "very scared" of an unreleased video that may further expose how it profits from aborted or even "born alive" babies, the man behind the exposè said.

David Daleiden of the Center for Medical Progress, who led the undercover investigation on Planned Parenthood, said the group made a shocking admission caught on video when its members met with the "top leadership" at StemExpress, a biotechnology firm that supposedly takes part in the harvesting of foetal tissue.

"In a meeting with their top leadership, they admitted that they sometimes get fully intact foetuses shipped to their laboratory from the abortion clinics they work with, and that could be prima facie evidence of born alive infants," Daleiden said.

"That's why they're trying to suppress that videotape and they're very scared of it," he added.

Earlier this week, a court in California issued a temporary restraining order preventing the Center for Medical Progress from releasing a video with StemExpress top executives.

The lead investigator added that eight to 10 more videos will be released to fully expose Planned Parenthood's alleged involvement in the sale of body parts of aborted babies.

"When people are using illegal abortion procedures, that's something that most people find barbaric and that's something that most people don't want funded by their taxpayer dollars," Daleiden said.

"We've got anywhere from eight to 10 more videos—the exact number could vary, but I predict a dozen, give or take, when everything is said and done," he added.

Daleiden's group has so far released four videos showing Planned Parenthood officials negotiating on the price of aborted baby parts, with one even demanding a luxury car for the deal.

Officials of Planned Parenthood, however, have earlier denied breaking any laws and all of Daleiden's allegations.
