A reward of up to $7,500 through 88-CRIME is being offered for information leading to an arrest in a sexual assault and kidnapping last month.
Detectives are asking the public for help in identifying the assailant who attacked a woman Feb. 27 at a midtown business in the 1600 block of North Swan Road, said Sgt. Pete Dugan, a Tucson Police Department spokesman.
The neighborhood is south of East Pima Street.
After the attack at about 8:30 p.m., the man kidnapped the woman and her 3-year-old son in the woman's car, Dugan said.
The woman had finished working and was preparing to leave. She buckled her son into the car seat in the vehicle, and went back inside the building to retrieve something she left behind, Dugan said. He said a man holding brass knuckles followed her inside.
The man threatened to hurt the woman if she didn't follow his directions, said Dugan. He said the man forced her into an office and sexually assaulted her.
Dugan said the man then demanded her car keys and he forced her into the car before driving away. When they were stopped at a traffic light at East Grant Road and North Mountain Avenue, a Tucson Fire Department truck approached with its emergency lights on, Dugan said.
The woman jumped out of the car and flagged down firefighters for help.
Meanwhile, the assailant drove off heading west with the woman's son in the back seat.
Sexual assault detectives and sex offender registration and tracking unit detectives went to the scene, and an Amber Alert was issued, Dugan said.
The car was found at about 1 a.m. in the 4400 block of East Water Street, and the boy was asleep and unharmed in the back seat, said Dugan.
The assailant, who was captured on surveillance video, is believed to be a white man who is between 40 to 50 years old. He has acne scars on his face, and is about 6 feet tall. He has a strong build.
Detectives ask anyone with information to call 88-CRIME, the anonymous tipster hotline.
