Travis County Sheriff's Office responded to the 911 call at about 5am local time. The caller said there was a shooter at the <a href="https://www.thenationalnews.com/business/2022/04/07/tesla-marks-opening-of-texas-gigafactory-with-flashy-celebration/" target="_blank">Tesla Gigafactory plant</a> in Austin, a sheriff's office spokesperson said. Workers inside the plant received an alert message saying, “There is an Active Attacker near column location 35Z at the Giga Factory Texas. Please take cover and stand by for further details.” Police cleared the large plant and found no shooter, threat or injuries, the spokesperson said. Tesla did not immediately respond to a request for comment. The nature of the phone call, including where it came from and who placed it, was being investigated by police, the sheriff's office said.
