4:52 PM: Thanks for the tips about police “in tactical gear” chasing a suspect just south of Admiral/California. So far as we know, this is a warrant arrest. An SFD engine was dispatched because the suspect claimed to have gotten hurt in the process. Working to find out more.
5:32 PM: The scene was clear when we got there, so we won’t be able to find out anything more until tomorrow.
ADDED 10:10 AM MONDAY: A commenter said last night that this was an arrest of another robbery-spree suspect; a check of the jail register this morning confirms that (updated) one of the additional potential suspects named in court documents was indeed booked last night. We’re asking SPD for confirmation about whether a “flashbang” – used in some warrant/standoff situations – is what led to the “explosion” noise some reported last night.
11:12 AM: SPD confirms that what was heard was a noise-making device used by SWAT. The warrant on which the 19-year-old suspect is being held, so far, actually is related to a case from last year. Meantime, today is the rush-charging deadline for the two “spree” suspects arrested Friday so we’ll have a separate update later.
