Update: Wildwood Mayor Ernie Troiano, Jr. spoke to NJ Advance Media on Monday about the arrest of Emily Weinman. "She refused to comply," he said. "Unfortunately, this is what happened."

Police in Wildwood say they have launched an internal affairs investigation after a video depicting an officer punching a 20-year-old Philadelphia woman during her arrest went viral on social media over the weekend.

In a statement Sunday evening, the Wildwood Police Department said the officers involved in the arrest Saturday of Emily Weinman have been reassigned to administrative duties pending the findings of a "full and thorough" investigation, which will be assisted by the Professional Standards Unit of the Cape May County Prosecutor's Office.

In the video, which was posted on Twitter Saturday afternoon, two officers can be seen trying to restrain Weinman on the sand as voices yell out, "Stop resisting!" One officer in the foreground of the footage can be seen raising his right hand in a fist and striking Weinman at least twice in the head.

In a Facebook post that has since been removed from public view, Weinman said she had alcohol on the beach when officers approached her regarding suspected underage drinking.

Weinman claimed she passed a breathalyzer test and was walking away when officers followed her, prompting her to ask whether they didn't have "something better to do" than stop suspected underage drinkers. She wrote that an officer tackled her after she refused to give police her name and started backing away.

"Chief (Robert) Regalbuto stated that while he finds this video to be alarming, he does not want to rush to any judgement until having the final results of the investigation," the department said in its statement, in which officials asked for witnesses to come forward.

Police said Weinman was charged with two counts of aggravated assault on a police officer, aggravated assault by spitting on an officer, disorderly conduct, resisting arrest and being a minor in possession of alcohol.

Weinman did not mention the criminal charges against her in the since-removed Facebook post. Wildwood's mayor, Ernie Troiano Jr., told Philly.com police would at some point release body camera footage showing the woman being combative with the officers.

Multiple attempts to reach Weinman for comment by phone, social media messages and in person Sunday were unsuccessful.

The original video posted to Twitter on Saturday had been retweeted more than 25,000 times as of late Sunday evening.

Police asked that anyone with "supporting video" of the encounter contact Detective Lt. Kenneth Gallagher at 609-522-0222.
