DETROIT (AP) — Police in Detroit are searching for men who allegedly robbed two young couples at gunpoint in separate attacks two hours apart and gang-raped the women while forcing the male victims to watch. There had been no arrests as of Sunday afternoon, police Sgt. Cassandra Lewis told The Associated Press. The second attack happened about two hours later and was almost identical to the first, except this time there were only four men who took part, the deputy chief said. Police released sketches of three of the suspects, including one who they are confident took part in both attacks.
