All three Tyler Super Wal-marts were evacuated Saturday night after authorities say someone called in a bomb threat. Around 8:30 p.m., shoppers at the Wal-mart on Troup Highway told KLTV 7 an announcement was made over the store's intercom to leave the building immediately. Shortly before that Wal-mart was evacuated, shoppers at the Wal-mart on South Broadway and Highway 64 were also asked to leave. Tyler fire investigators say all three Wal-marts were searched and no bomb was found. No arrests have been made at this time.
