A man suspected of breaking into woman's dorm room has been arrested. 

Justin Chiou, 18, is behind bars, suspected initially of stealing a key card from a female student.

"He went into the girl's bathroom and stole my card," She Ming Cheng told News10. 

She says Chiou used that card to break into Potter Hall and gain access to the dorm room of a friend. He climbed into bed with the student.

"That morning, he went back in one of the girls dorms. And when the girls woke up, he's already in her bed," she said. 

The girls screamed and Chiou fled.  

He was captured after his picture, caught on a security camera, was spread around campus and on social media.  

UC Davis officials held a meeting with rattled students to discuss dorm security following the incident.
