A community of multi-million-dollar homes was besieged by law enforcement searching for one seriously bad dude today, Sheriff's officials said.

The hunt for 54-year-old Oscar Bridges in the terrain above the Greek Theater and near Runyon Canyon Park involved a helicopter, cops on horseback and nearly 50 deputies on the ground, the L.A. County Sheriff's Department said.

But the search was called off early this afternoon, we were told:

Sheriff's spokeswoman Nicole Nishida said deputies came up empty. 

Cops believed Bridges, who appeared to lead somewhat of a transient lifestyle, might be in the hills or at motels, shelters or churches lining the Hollywood Boulevard corridor below, she said:

We did get tips that he was seen in the area – motels, shelters, churches. We went to local motels and handed out fliers.

Search teams gathered at the Hollywood Bowl this morning before fanning out, deputies said.

Detectives allege that Bridges fatally stabbed 21-year-old victim Robert Brewer of Texas in the room of a motel in the 10400 Block of South Vermont Avenue in South L.A. County territory Jan. 23.

The attack was reported at 10:40 a.m., deputies said. Brewer was pronounced dead at the scene.

Investigators say Bridges is known on the street as Rick. He's 6 feet, 2 inches, 180 pounds with dreadlocks. Cops say he frequents motels in Hollywood and West Hollywood.

Deputies alleged this in a statement:

He is considered armed and dangerous with an extensive criminal record and is a registered sex offender. 

If you've seen him recently call detectives at (323) 890-5500.
