RIVIERA BEACH, Fla. - A Riviera Beach man is being held in the Palm Beach Jail after police said he sent a threatening email to Walgreens.
Police said the suspect, Robert Warn, had been arrested three years ago for assaulting a man outside the same Walgreens, which is located at 2501 Broadway.
The manager of the store says that Warn was recently told by an employee that he could not go into the store.
According to the manager, Warn then became very irate and left the store.
Police said that Warn then sent an email to Corporate Consumer Relations for Walgreens stating that, "We are not doing anything to the manager but we could do something to their vehicle because I know where they all park or even blow up the building."
The manager of the store told police he was concerned for the safety of his employees.
Warn was arrested by the Riviera Beach Police for making a bomb threat.
