WOODBRIDGE — One of two men sought in connection with an armed robbery and sexual assault of a couple was arrested Tuesday, according to Middlesex County Prosecutor Yolanda Ciccone. Razzell Austin, 21, was arrested in the Avenel section a day after the prosecutor's office released sketches of the people they say are responsible for the April 16 incident in the area of Lee Street and Scott Place in the Port Reading section. The other man has not been arrested. He is described as slim, between 5 foot 5 inches and 5 foot 9 inches with brown hair and brown eyes wearing a gray Nike hoodie and white Nike sneakers at the time of the assault.
