KTLA: Anaheim Police detectives have arrested a 33-year-old man suspected of sexually assaulting a 12-year-old girl he met on the social networking site MySpace.

Matthew Casteneda was taken into custody Friday night at a warehouse in the 2000 block of Placentia Avenue in Costa Mesa.

He was booked in the Anaheim Detention Facility for lewd and lascivious behavior with a child under the age of 14.

The girl was found at an Anaheim hotel, just outside Disneyland, about two and a half hours after being reported missing in Santa Ana on Wednesday.

Investigators say the girl told officers she had been sexually assaulted by a man she met through MySpace.

"They met at South Coast Plaza and took a bus up to Anaheim, where he took her to a hotel and sexually assaulted her," said Santa Ana police Cpl. Anthony Bertagna.

Anaheim police Sgt. Tim Schmidt said the girl was located after she flagged down an Anaheim Police Department employee.

The case is in the early stages of investigation, Schmidt said.

Police believe Casteneda has victimized other minors, and asked anyone with more information to contact detectives at (714) 765-1958.
