Dallas police have arrested a 59-year-old man in the sexual assault and beating of a 17-year-old girl.
One person is in custody after a teenage girl was raped and badly beaten on the way to school Wednesday.
Dallas police said they arrested 59-year-old Tommy Robinson, aka Tommy King, on suspicion of aggravated sexual assault. Police said Robinson has been extremely uncooperative in the investigation.
According to Dallas police, the 17-year-old girl was headed to a Dallas Area Rapid Transit bus stop in the 4700 block of Maple Avenue at about 7:30 a.m. when she was approached and attacked.
"I think it was a situation where she happened to cross his path at the wrong time, and this individual is obviously very dangerous," Lt. David Pughes said.
Surveillance video from a nearby liquor store shows a man dressed all in black run up behind the girl and grab her. The victim was stabbed several times during the sexual assault.
An hour later, Quintanilla Furniture store employees found the girl nude, badly beaten, bloody and mumbling inside a fenced in area around a trash bin.
"Her face was -- she was so swollen that we can't really tell, you know, who she was," said Ivan Garcia, who found the girl.
The teenager was transported to a local hospital, where she was in critical but stable condition Wednesday night.
Pughes praised the teenager for describing her attacker as she was being rushed to the hospital.
Dallas police officers immediately began searching for the attacker. With Air One overhead, officers searched the area until about 11 a.m., when they found a man matching the description of the attacker bathing in creek bed west of Maple Avenue -- only a block north of where the girl was found.
"The question then becomes, 'Is he taking a bath, or is he trying to wash off evidence?'" Pughes said.
Robinson is being held in the Lew Sterrett Justice Center on a $500,000 bond. Police have asked that NBC 5 not show his face until after a photo lineup.
The Dallas Independent School District confirmed the girl was a student but did not release the name of her school to protect her privacy. Additionally, the district is not sending counselors to school or letters home to parents about what took place.
