The Los Angeles Police Department (LAPD) has said no police report has been filed after Oscar-winner Will Smith stuck comedian Chris Rock on stage at Sunday night's Oscar ceremony.

"LAPD investigative entities are aware of an incident between two individuals during the Academy Awards programme," an LAPD spokesperson told the PA news agency.

"The incident involved one individual slapping another. The individual involved has declined to file a police report.

"If the involved party desires a police report at a later date, LAPD will be available to complete an investigative report."

The incident has left Hollywood reeling.

Will Smith's son Jaden and tennis star Serena Williams are among the stars who expressed both shock and support after the shocking altercation between Smith and Rock.

Smith appeared to take offence at a gag comedian Rock made about his wife Jada Pinkett Smith’s short haircut before taking to the stage and striking him in front of the star-studded audience at the Dolby Theatre in Los Angeles.

Red Table Talk host Pinkett Smith has previously spoken about her struggles with alopecia and said it is what prompted her to shave her head.

Will Smith took the Best Actor award for his role in King Richard

After being named best actor for his performance as the father of Williams and her sister Venus in King Richard, Smith used his acceptance speech to apologise to the Academy and "all my fellow nominees" - but not Rock.

"I’m being called on in my life to love people and to protect people and to be a river to my people," he added.

Shortly after the incident, Serena Williams shared a video on her Instagram story showing her looking shocked.

In a second clip, the sportswoman admitted she "had to put her drink down".

Jaden Smith, 23, tweeted: "And That’s How We Do It" after his father’s on-stage altercation.

He later told his followers that his father’s acceptance speech had made him cry.

Rapper 50 Cent shared a photo of the moment on Instagram and wrote: "B!tch don’t you ever play with me. LOL."

American late-night talk show host Conan O’Brien was among those making light of the situation, writing on Twitter: "Just saw the Will Smith slap.

"Anyone have a late night show I can borrow just for tomorrow?"

However, Smith’s actions also attracted criticism from members of the film industry.

The Last Samurai producer Marshall Herskovitz urged the Academy to do more than simply issue a statement in response to the incident.

He said on Twitter: "I call upon the Academy, of which I am a member, to take disciplinary action against Will Smith.

"He disgraced our entire community tonight."

Hollywood star Mia Farrow tweeted: "It was just a joke. Jokes are what Chris Rock does.

"Always has been edgy. This was a mild joke for him. And I love GI Jane."

Referring to words from Smith’s acceptance speech, English actor Cary Elwes said: "The 'vessels of love’ I have known or admired never acted violently against another human being…"

One Tree Hill star Sophia Bush commented that "violence isn’t OK".
