RICHMOND — Police today arrested a man they consider a main participant in the Oct. 24 gang rape of a 15-year-old student outside a Richmond high homecoming dance, while prosecutors filed charges against a fifth person.

Richmond officers raided a home on the 2500 block of Pine Street about 7 a.m. and arrested 21-year-old Elvis Josue Torrentes without incident, Lt. Mark Gagan said. Detectives used a probable cause arrest warrant; he is held in lieu of $1.25 million bail on suspicion of several sexual assault charges. Prosecutors will consider charges against Torrentes on Thursday.

Later today, suspect Jose Carlos Montano, an 18-year-old Richmond resident arrested last week, wiped away tears as bailiffs
