From Cerritos Sheriff’s Facebook
An MK-2 WWII era grenade was discovered in a pile of donated clothing by Goodwill store employees. Cerritos Station deputies evacuated neighboring businesses and called in LASD Arson/Explosives detectives. No threats of any kind were ever made to Goodwill or its employees. It was determined by Arson/Explosives personnel that the grenade was inert, and that no one was ever in danger.
