LOS ANGELES (CBSLA.com) — A UCLA fraternity member has been arrested for the attempted murder of a female party guest at the Theta Chi house.

Authorities said Paul Meyer, who reportedly lives at the Theta Chi house located in the 600 block of Gayley Avenue, attempted to strangle a female student who was attending the party.

The alleged attack took place early Friday morning, about 2:30.

Campus police said Meyer, 20, and the unidentified victim were acquainted with each other prior to the incident.

Investigators have yet to determine what would have caused Meyer to become violent with someone he knew.

The alleged victim was taken to a hospital. She was treated and released.

Meyer, a chemical and biomolecular major, was also taken to a hospital to be treated for an unspecified illness.

Neighbor Ariel Epstein-Norris saw five detectives going in and out of the house. “It made me wonder, what is happening,” she said.

Daniella Abrams said the incident was scary especially because it involved another student.

When CBS2 reporter Cristy Fajardo went to the Theta Chi house for a comment she was told to get off the property.

The UCLA chapter of Theta Chi made news in November 2011 when a person visiting the house was found dead of a suspected overdose.
