The Los Angeles Police Department has launched an investigation into the shooting of Nine Network journalist Lauren Tomasi, who was struck by a rubber bullet during protests in the city on Monday.

Tomasi, who serves as the United States correspondent for the network, reported that she is 'a bit sore but okay' following the incident.

The protests, which have garnered widespread attention, marked their fourth consecutive day.

Nine Network CEO Matt Stanton confirmed the commencement of the investigation, following statements from Los Angeles Police Chief Jim McDonnell.

McDonnell acknowledged troubling reports concerning media personnel being injured by crowd-control munitions and committed to examining the circumstances surrounding these incidents.

Although he did not directly reference Tomasi, he expressed concern over the possibility of harm to journalists during the unrest.

Stanton described the video footage of the incident as disturbing, suggesting it raised critical questions regarding the justification for police actions.

He stated the importance of a thorough investigation to clarify what transpired and why, and indicated plans to reach out to the LAPD Commissioner to offer cooperation.

Australian Prime Minister Anthony Albanese addressed the situation in a speech at the National Press Club, revealing that he had communicated with Tomasi and discussed the incident with U.S. authorities.

He characterized the footage showing the police officer seemingly targeting Tomasi as 'horrific' and emphasized the need to protect journalists making media coverage during events of unrest.

Albanese conveyed that it is unacceptable for a journalist to be deliberately targeted, and reaffirmed the crucial role of the media in society.

He noted that discussions about the issue had been raised with the U.S. administration, expressing his displeasure regarding the incident.

Responding to media inquiries, McDonnell reiterated the department's concern about journalists being struck by crowd-control munitions, and outlined strategies aimed at safeguarding non-combatants during protests.

He acknowledged the complexities involved in ensuring such protections in fluid situations, emphasizing the importance of targeted munitions while acknowledging the unpredictability of their deployment.

Tomasi provided an update on social media, thanking supporters and describing her experience.

During an appearance on Nine's Today program, she recounted the sequence of events leading to the incident, explaining that police were pushing through the area while deploying tear gas and rubber bullets.

While focused on reporting, she was struck by a projectile, which she described as leaving a significant bruise.

The deployment of the National Guard in Los Angeles is part of broader measures taken to manage ongoing demonstrations, reflecting the heightened tensions in the area.

The investigation into the incident will examine the actions of law enforcement and the protocols surrounding the use of crowd-control munitions in the context of public protests.
