Whoops.

Footage capturing the outside of Jeffrey Epstein’s cell during his first suicide attempt is not missing, prosecutors said Thursday — correcting the bombshell assertion Wednesday that it was.

“Earlier today, the Government confirmed with [Metropolitan Correctional Center] staff that the Video was preserved by MCC staff,” Assistant US Attorneys Jason Swergold and Maurene Comey told federal judge Kenneth Karas in a court filing.

The revelation comes a day after Swergold stood up in court and claimed that the footage hadn’t been retained by the facility, despite a request from a lawyer for Epstein’s former cellmate Nicholas Tartaglione.

Tartaglione, who is awaiting trial for quadruple homicide, was sharing a cell with the now-dead pedophile on July 23 when he first tried to take his own life.

Tartaglione has told The Post via letter that he immediately called for help, and his attorney Bruce Barket says his client has been cleared of any wrongdoing in the incident.

Epstein was found hanged in his cell in August, and his death was ruled a suicide.
