… at Johnny's Liquor on Fair Oaks.  Relayed from sheriff's liaison Carolyn Seitz:

Lieutenant Sanchez indicated there were multiple calls to the [Altadena Sheriff's] Station reporting a large gathering of gang members and that about ten were fighting.

All of the people standing around outside the store were detained at gunpoint. 

Ultimately no arrests were made.  That would mean there were no outstanding warrants for any of the people detained, no weapons or drugs found.
