Internet authorities in China's Tianjin city slapped a fine of 300,000 yuan ($44,720) on the company for violating the country's cyber security laws, Visual China said in a filing to the Shenzhen stock exchange.

On Friday, Visual China, which partners with U.S. photo agency Getty Images, shut its website and apologised after it falsely claimed copyright of images such as the first photo of a black hole and China's national flag. The news had caused its shares to slump by the maximum 10 percent daily limit.

On Thursday, its shares closed 4.4 percent lower, lagging the performance of broader Chinese stock indices.
