Both westbound and eastbound lanes of Interstate Highway 580 are now open after a bomb squad detonated a suspicious package found today in a pickup truck belonging to a man involved in an early-morning shootout with CHP officers, according to a California Highway Patrol officer.CHP officers attempted to stop the driver shortly after midnight this morning after observing a white Toyota truck allegedly speeding and weaving through traffic on westbound Interstate 580 near the Grand Avenue exit.After conducting a routine traffic stop, the driver did not respond when CHP officers tried directing him off the freeway with their loudspeaker, Oakland police said. CHP officers then approached the vehicle and allegedly saw firearms inside and the driver arming himself. He was allegedly armed with a handgun, shotgun, rifle and body armor. The suspect, described as a 45-year-old man, allegedly fired at officers as they moved back to their marked vehicles and CHP officers returned fire, Oakland police said.Two CHP officers were transported to a local hospital and treated for minor injuries after the exchange.The suspect was shot an unknown number of times and was listed in stable condition this afternoon, Oakland police said. He is under arrest for attempted murder.”This person blatantly and randomly shot at our officers without provocation,” Morgan said.The CHP officers involved in the shooting were placed on administrative leave, which is standard procedure, Morgan said.”This was a very aggressive person,” Morgan said. “He shot at officers on a freeway that was opened to the public. Clearly his intentions were less than honorable.”Oakland Homicide is conducting a criminal investigation, and CHP is conducting an administrative investigation into the incident.After the shootout, CHP officers and Oakland Homicide investigators found a suspicious package along with a binder while searching the truck, which was sitting in the westbound lanes of Highway 580 west of Harrison Street, said CHP spokesman Sam Morgan.The Alameda County Sheriff’s Office Explosive Ordinance Disposal Squad was called to assist after the suspicious items were found inside the truck, Morgan said.A member of the bomb squad who was wearing a protective suit to search the truck could not confirm that the package was non-destructive, Morgan said. A robot was then used to retrieve the package, which was detonated in the westbound lanes of Interstate 580 near Harrison Street.Investigators also found a white binder with the word “California” on the front in the truck, Morgan said. Investigators do not know the full significance of the binder.”It’s like a piece of the puzzle,” Morgan said.The bomb squad remained on the scene for several hours but had left the area by 4:30 p.m., Morgan said.The shootout forced the closing of Interstate 580 in both directions and Interstate 980 and some surrounding exits for several hours. Eastbound lanes were reopened as of around 6 p.m., and the westbound lanes were opened at around 7 p.m.
