[UPDATE II: Suspicious device turned out to be "an old military-grade artillery shell." Egads. SF Appeal reports, "Police contacted Travis Air Force Base, which is sending technicians to determine the exact nature of the device." ] At around 10:45 a.m. today, a suspicious device was found near Channel and Fourth Streets near AT&T Park. Authorities have since closed the area: streets are closed, two buildings have been evacuated, and residents along the waterfront living in houseboats have been asked to leave the area.

We'll update as soon as we know more.

Update I: On/Offramp to 280 along King Street has been closed. Motorists are advised to consult 511.org to identify alternate routes.

According to CBS 5 (interrupting us right in the middle of The People's Court, no less!) "East Contra Costa County residents are being evacuated from an area near the unincorporated town of Knightsen because of a possible explosive device found inside of a residential motor home."

Motor homes and explosive devices? Who could've imagined!? Anyway, that's all the info posted so far. We'll update as soon as more info becomes available.

Update: Taken (again!) from CBS 5: "Sheriff's spokesman Jimmy Lee said the device was found about 1:30 p.m. on Broadway by a man who said the device looked like dynamite.The bomb squad from the Walnut Creek Police Department responded and residents within a 1-mile radius of Broadway were ordered to evacuate."

Emergency telephone alert calls were made to "220 residents" living in the area, and the evacuees were sent to Delta Vista Middle School.
