Working with Mateen at the St. Lucie County Courthouse in 2013, a co-worker said he had complained to superiors at G4S about Mateen's frequent violent, racist and homophobic tirades, but that the company ignored him. G4S denied having a record of those complaints. After Mateen claimed to his co-workers a family connection to Al Qaeda and said he was a member of Hezbollah, the county sheriff's office called in the Federal Bureau of Investigation. The St Lucie Sheriff's office "demanded" Mateen no longer provide security for the Courthouse. When G4S became aware the FBI was investigating Mateen, they did not dismiss Mateen but transferred him to the south guardhouse of the PGA Village, a gated community in Palm Beach County.
