Three more Rikers Island jail guards have been convicted of charges in connection with an attack on an inmate who stared down a jail chief.

Captain Gerald Vaughn was convicted of attempted gang assault and other charges Friday. Two officers, Harmon Frierson and Dwayne Maynard, were convicted of misdemeanor official misconduct charges.

On Tuesday, four officers and an assistant chief were convicted of felony charges in connection with the June 2012 attack.

Prosecutors said the chief had ordered several officers to attack Jahmal Lightfoot after the inmate stared him down.

Authorities say Lightfoot suffered two broken eye sockets and other injuries. Prosecutors alleged the guards also falsified reports to say Lightfoot had a weapon.

The president of the union that represents city correction officers says the verdict is "outrageous."
