After several Los Angeles Police Department (LAPD) officers were injured by rioters during anti-ICE protests in Los Angeles on Sunday and Monday without arrests made, the department's largest union representing most rank-and-file officers hopes the "communication break-down" will be investigated.

In a statement to Fox News Digital , the Los Angeles Police Protective League said "the arrest of individuals that are attacking police officers should be a no-brainer for any competent incident commander."

"Apparently, that did not happen yesterday," they said.

"When those committing violence against anyone, let alone police officers, are allowed to masquerade as peaceful protesters, it sends the wrong message and crushes officer morale," the board said. "We hope this incident is investigated with the same vigor as past crowd control incidents were investigated and those that allowed officers to be attacked are held accountable."

While no arrests were made on Monday, LAPD Chief of Police Jim McDonnell said no stand-down order was given.

"The LAPD closely monitored the situation and the Incident Commander made decisions that prioritized public and officer safety," McDonnell said in a statement provided to Fox News Digital.

Meanwhile, the incident commander on sight on Monday, Lillian Carranza, told Fox News Digital that "the minute officers were attacked it became an unlawful assembly."

She added, "Of course we will make any lawful arrest that the officer can make safely," she said. "The officers must observe and attest to the violation. I fully support any citations or bookings that officers make."
