PHOENIX (3TV/CBS 5) -- Arizona State University is trying to get to the bottom of why nine students from China were detained by Customs and Border Patrol at LAX.
ASU said the students were flying back to Arizona to attend the fall semester when they were stopped and detained by Customs and Border Patrol at LAX in Los Angeles.
Spokesman Jerry Gonzalez said the students were academically eligible to return to ASU and to the United States under their visas.
"To ASU's knowledge, the detentions were not based on allegations of academic dishonesty. Customs and Border Protection has not told ASU it was related to academic dishonesty -- in fact, CBP has given ASU no information on what has transpired," Gonzalez said in a statement to Arizona's Family.
US Customs and Border Protection said, "The Chinese students were deemed inadmissible to the United States based on information discovered during the CBP inspection."
Bo Li is an ASU student from central China. He is not one of the nine detained, but said it's a scary situation.
"...they just verify my name and date of birth and let me go. So, it's quite easy," said Li when describing his encounters flying into the US. "I don't know the situation with the nine students."
US Customs and Border Protection has not gone into detail about what information it discovered leading to this.
"I'm a little bit concerned because if I were them, I'd go out of the United States and re-enter," said Li. "If I was denied to enter the US, I think it's reasonable for the government to give specific reasons and evidence."
