A former Harvard-Westlake classmate who wished to remain anonymous said they were shocked by the photo, but added that Martin had talked about suicide in the past and has also previously used his social media accounts to post "disturbing" messages. A post on Martin's Instagram account appears to have shut down a Los Angeles high school on Friday.
Students at Harvard-Westlake High in Studio City received an alert before school began Friday stating the school was closed. "With these precautions in place, we believe there is no imminent threat to our campuses or our school community".
One source at Harvard-Westlake said Martin has been detained over the incident, though police said there was "no credible threat" against students.

He declined to confirm that the man is Martin or to explain the meaning of "detained", which he said does not necessarily mean Martin is in jail or police custody.
