Police in India on Thursday were preparing to charge three men detained in connection with the gang rape of a 31-year-old California woman who hitched a ride in a truck, NBC News reported. Investigators obtained a cellphone number believed to belong to the principal suspect and used it to track down the men, said B. Kamal Kumar, director of police in the northern state of Himachal Pradesh. “With the help of this number we check out the previous calls,” he said. “It helped a lot in tracing the [suspects].” Kumar said the victim identified all three men in a police lineup. “Two of them were locals and our team of special police found them,” Kumar said. “The other fellow was trying to escape through a nearby town ... He was caught at a checkpoint.” The victim, earlier said by police to have been between 35 and 40, had been visited by U.S. diplomatic officials and was said to be “all right,” Kumar said.
