There is a storm over a police video that has appeared on social media in Myanmar.

At least four officers have been detained by over footage that appears to show police beating members of the Rohingya Muslim minority.

The images, filmed by an officer involved in the rounding up of villagers,have been widely shown on social media and by Myanmar broadcasters.

Authorities promised to take action after the video emerged, apparently filmed during a crackdown in Rakhine State, which borders Bangladesh in the country’s northwest.

Police have been hunting for suspects after nine officers were killed in attacks by gunmen on border posts in October.

Thousands of Rohingya Muslims are reported to have fled into Bangladesh.

Rights groups say residents have complained about killings and abuse, including rape, accusations denied by the government.
