There are calls for an investigation after a Christian leader died in police custody. Vam Ngaij Vaj died on March 17th in Vietnam, after being arrested for allegedly 'destroying the forest'. Police claimed he died after putting his hand in an electric socket but photos reportedly show many bruises on his body. Premier spoke to a researcher from Christian Solidarity Worldwide, who can't be named for security reasons. She says they suspect he's one of many Christians in Vietnam who face persecution for their beliefs.
