NEW ORLEANS -- Police released a composite sketch of a suspect wanted for kidnapping a Tulane student early Sunday morning.

The suspect is wanted for second-degree kidnapping and sexual battery, police said.

Around 4:15 a.m., the female student was walking near the intersection of Broadway and Freret streets when a vehicle pulled up beside her. A man got out of a silver-colored car and told the student, "I have a gun, don't resist," then forced her into the back seat of his vehicle.

The student said that he assumed she was a prostitute and demanded sex from her. After she explained she was a Tulane student and not a prostitute, he dropped her off in the 8200 block of Willow Street after driving her to Interstate 10 and Causeway Boulevard in Metairie. The suspect slapped the victim on the buttocks as she exited the car, police said.

The suspect is described as being in his mid to late 30s, approximately 6-feet and weighing around 250 pounds. He is bald, has a light to medium complexion, and was wearing a Polo style shirt and dark colored jeans.

Anyone with information is asked to call Crimestoppers at 504-822-1111.
