Four employees of a company that provides security at Honolulu International Airport have been indicted for taking bribes.

State Attorney General Doug Chin says an Oahu grand jury indicted the Securitas employees Thursday.

Deputy Attorney General Albert Cook says the men allegedly solicited and accepted more than $3,000 in bribes from taxi and shuttle drivers at the airport. In exchange, the drivers were allowed to circumvent ground transportation rules at the airport.

Chin says the indictments are the result of a monthslong undercover investigation by his office and the FBI. Chin says taxi drivers complained about certain officers showing favoritism to those willing to pay bribes.

Securitas officials didn't immediately return a phone call from The Associated Press seeking comment.
