(CNN) - The Broward County Sheriff's Office has placed a second officer who responded to the Parkland, Florida school shooting on "restrictive duty," spokesperson Gina Carter told CNN.
The sheriff's office did not give a reason for the restrictions placed on deputy Edward Eason, which will last while an internal review is conducted.
Eason must surrender his badge and weapon and may not drive a sheriff's vehicle or enter a department building, according to a memo released Friday. The memo didn't say what his duties would be.
The sheriff's office told CNN that the discipline against Eason was due to testimony presented to the Marjory Stoneman Douglas High School Public Safety Commission this month.
The hearings revealed communication breakdowns among law enforcement and school staff as the shooting unfolded. Seventeen students and teachers were killed.
The commission also heard about overlooked warning signs regarding the alleged gunman.
Deputies association files grievance
Jeff Bell, president of the Broward Sheriff's Office Deputies Association, told CNN that Eason was placed on restricted duity without explanation and was not told that the change was due to the testimony to the safety commission.
Bell said the association is filing a grievance on Eason's behalf.
"If it has anything to do with the testimony from the hearing, shouldn't the sheriff [Scott Israel] be removed?" Bell said. "What about the inaccuracies of the sheriff? Shouldn't he be placed on restricted duty?"
This is not the first time Bell has asked for Israel's removal. In April, the union conducted and declared a vote of no confidence in the sheriff. In May, the union paid for billboards asking the governor to remove Israel.
In February, the sheriff's office said Eason was being investigated for his actions during calls to accused gunman Nikolas Cruz's home before the shooting.
Bell said Eason had been returned to full duty after that investigation.
School resource officer resigned
The first officer to be disciplined, Scot Peterson, was the school resource officer at Marjory Stoneman Douglas High School. He was suspended without pay for waiting outside during the shooting, and he resigned not long after.
Capt. Jan Jordan, who was in charge during the shooting, resigned last week during the hearings.
Cruz, 20, has been in jail since the shooting at his former school. Cruz confessed to carrying out one of the deadliest mass shootings in recent US history, court documents show.
He is charged with 17 counts of first-degree premeditated murder and 17 counts of first-degree attempted murder.
Earlier this week, Broward schools announced that Assistant Principals Jeff Morford, Winfred Porter Jr. and Denise Reed, and Security Specialist Kelvin Greenleaf would be reassigned to other administrative locations in the district.
