A woman in Shenyang, Northeast China's Liaoning Province has been put under police investigation after broadcasting live her damaging of products in a local Lotte Mart supermarket on Sunday.

A report Sunday on Beijing-based news site btime.com identified the suspected vandalizer in a 49-second viral video from Kuaishou Zhibo, a Chinese live streaming platform, as a platform user going by the name "sipingraoge."

The woman wearing black clothes enters a Lotte Mart supermarket and crushes instant noodle packs, steals snacks and drinks up beverages without paying, the video shows.

The suspect shows her insulting fingers to the camera as her curtain call with the song "zhonguoren," or "Chinese people," playing in the background, said the report.

The live streaming platform issued a statement later on Sunday on its official Sina Weibo account, saying that the company has already noticed the misconduct, and the evidence has been gathered and handed to the police for further investigation.

"The case is being probed," said a Shenyang police officer on his Weibo account "Shenyang Wangjing Xiaopang" on Sunday.

"You have to be rational first before being patriotic. It is either stupid or malicious if one disgraces the country in the name of patriotism," the officer noted.

Chinese companies and the general public have been taking action to boycott South Korea's Lotte Group amid mounting anger over the company's land-swap deal with the South Korean military for the deployment of the US anti-missile system, Terminal High Altitude Area Defense.

Some have rushed to social media platforms like Weibo to express their dissatisfaction.
