UPDATE: Suspect Arrested in Brutal Beating of Giants Fan at Dodger Stadium

Police have now formally arrested a man suspected of being one of the two who attacked Bryan Stow March 31 at Dodger Stadium.

Thirty-one-year-old Giovanni Ramirez is being held on $1 million bail after being charged with assault with a deadly weapon.

According to Captain Bill Murphy of the LAPD's Northeast Division, Ramirez was apprehended along with four or five others early Sunday morning, who have not been arrested.

They were taken at a three-story apartment on Mariposa Street straddling the Rampart and Hollywood LAPD divisions, just blocks from where the second day of the Silver Lake Jubilee art and music festival would take place.

Several SWAT units-- a total of about 60 officers--were brought to the scene about 7 a.m Sunday morning, although the man and the others surrendered peacefully.

At a press conference Sunday afternoon at Dodger Stadium, Mayor Antonio Villaraigosa, Council member Ed Reyes and LAPD Chief Charlie Beck called for the swift arrest of the remaining male suspect, as well as the woman who drove them away from the stadium.

Reyes and Villaraigosa made special pleas in Spanish for help finding the other suspects.

They also both commended the Stow family for their bravery and the Dodger organization for their cooperation..

Visibly moved, Beck called news about the suspect's apprehension about "the call he had been waiting for."

And LAPD spokesperson told Echo Park Patch that the $250,000 reward being offered remains in effect until the other suspects are brought in.

According to the Los Angeles Times, a parole officer supervising the man arrested noticed that he had covered up distinctive tattoos with additional artwork recently.

The parole officer became suspicious and alerted the LAPD. 

According to the Times, the suspect in custody has at least three prior convictions.  He was convicted of attempted robbery in 1998, robbery in 1999, and firing a weapon in a public place in 2005, according to the Times' source.

Just after the conference, Dodger owner Frank McCourt released a statement pledging to continue to cooperate with law enforcement through the prosecution.
