Police in Pleasant Hill cordoned off a section of Longbrook Way in their city Friday while investigating the apparent discovery of explosives or the ingredients needed to make an explosive in a local apartment.
The discovery was apparently made while police were investigating earlier – unspecified – vandalisms in Pleasant Hill and Clayton. Clayton PD officers were on hand when an explosive device and materials used to make similar devices were apparently located and the 27-year-old subject of the investigation was taken into custody.
The suspect’s name was not provided.
Neighbors said evacuation and “shelter in place” orders were issued for the occupants of about 20 apartment units in the 300 block of Longbrook as the scene unfolded, investigators calling for the Walnut Creek bomb squad truck and Hazmat personnel.
Police lifted their lockdown shortly after 7 p.m.
