Local Muslim leaders say the criminals' m.o. puts Muslims in harm's way.
"They put our women in danger of being of being stereotyped, victimized and ostracized by society," said Iman Isa Abdul Mateen, who is with the Majlis Ash'shura of Philadelphia, a Muslim advisory council. "Such cowardly, repugnant criminals are a plague upon Philadelphia."
"For cowards to dress up as women and perpetrate a crime is absolutely wrong," added 4th District Councilman Curtis Jones.
District Attorney Seth Williams is asking citizens to step forward.
"Give us information that leads to the arrest and conviction of the cowards that dress as women in garb in a way that helps them commit their evil crimes," said Williams, according to CBSPhilly.
Anyone with information is urged to call the Majlis Ash'shura at 215-474-0726.
