In the Wake of last week’s school shooting in Southern California that took the lives of two high school students, Arroyo Grande Police have arrested a 17-year-old boy for making threats against Arroyo Grande High School. According to a press release, authorities were made aware of a social media threat on Friday. The threat included a picture of the suspect and what appeared to be a 1911 handgun. An investigation led to the boy’s arrest early Saturday morning. He was booked on suspicion of making criminal threats. The weapon in the picture turned out to be a BB gun.
