(KRON) -- A 19-year-old San Jose man who allegedly manufactured ghost guns and used social media to sell them was arrested last week, the San Jose Police Department announced. SJPD said detectives with the department's Gun and Hazardous Suppression Team (GHOST) discovered a social media account on October 30 being used to buy and sell illegal firearms. GHOST detectives investigated the account and identified the suspect as Lucien Cabrera. Many of the firearms, according to police, were privately made firearms, commonly known as ghost guns. Cabrera, police said, was also importing high-capacity magazines from Florida and Nevada to sell in San Jose.
