Man Arrested After Teen Cosplayer Discovered 'Unconscious And Bloody' On The Side Of The Road At Comic-Con

Update: Police say the teen cosplayer wasn't brutally attacked, but suffered a nasty fall.
A man has been arrested in the case of a teenage cosplayer at Comic-Con who was discovered "unconscious and bloody" on the side of the road early Sunday morning.
A friend posted a message from the mother of the victim on Tumblr, asking for help finding out what happened to her daughter (we have redacted any identifying information since the girl is a teen and may be the victim of a sexual crime):
IF YOU WENT TO SAN DIEGO COMIC CON OR KNOW ANYONE WHO HAS, PLEASE READ. One of my dearest friends was found on the side of the road, unconscious and bloody. She was wearing this cosplay on the day it happened. She was last seen with friends when she ran off after a disagreement. Please, please, please, if you have ANY information or saw her anywhere, contact her mother. The full information is down below. This isn’t okay and it’s sickening to know that this happened at a place people truly can enjoy themselves. Please spread the word.
”I just received a call from the San Diego Police Department and my daughter [redacted] aka [redacted] was found on the side of the road covered in blood with no ID unconscious. They are unsure what happened to her. My husband is on his way to the police station and then the hospital. If you have any information on what happened to her please send me a facebook message or call me at [redacted]. Thank you in advance”. -[Mother's name redacted]
The victim was transported to a hospital for evaluation and treatment. The San Diego Harbor Police Investigations Unit is investigating the case.
