The suspect barricaded himself inside the supermarket with an unknown number of people, but was taken into custody “without incident,” according to police. “We have successfully taken the suspect into custody without incident. The situation remains fluid as officers move forward clearing the location,” the Los Angeles Police Department wrote on its official Twitter account US President Donald Trump had earlier tweeted that he was “watching Los Angeles possible hostage situation very closely.” Devin Field, a man who said he was walking into the store when the incident unfolded, described his experience in a series of tweets. “I was walking in when a car crashed running from the police crashed into street lamp in front of the entrance. Gunman got out and started shooting at the cops. I hid behind a retaining wall with three cops until they had me crawl out,” wrote Field, whose Twitter account identifies him as a writer for the Jimmy Kimmel Live TV show. “Gunman walked in shooting. He went into the back and took hostages. Employees snuck out through back emergency exits. Employee says blood was all over the floor, unclear from where,” he wrote.
