Police said no other information on the alleged attack would be released Saturday to protect the victims and the integrity of the ongoing investigation. Authorities declined to say give even general locations for the party and alleged crime scene and also wouldn't say when DeCoatsworth was arrested.
A listed number for DeCoatsworth has been disconnected and it was unclear whether he had an attorney.
Police Commissioner Charles Ramsey told a Philadelphia Daily News columnist in February of last year that he believed he had made a mistake in granting the former officer's request to go back to work too soon after he was shot.
"God bless him for still wanting to get out there and do police work, but did I act in his best interest? In hindsight, I would say probably not," Ramsey told columnist Sty Bykofsky.
