The Immigration Bureau has withdrawn visas issued for two CNN reporters after they entered the childcare centre where a mass shooting took place to report on the story.
The Immigration Bureau said on Sunday the visas for the two crew members had been revoked.
They entered Thailand on tourist visas which did not allow them to work in the country, the bureau said.
The officer referred to reporter Anna Coren, 47, an Australian citizen, and cameraman Daniel Hodge, 34, a British national.
Ms Coren and Mr Hodge were assigned to cover the massacre at the daycare centre in Nong Bua Lam Phu on Thursday. They trespassed the crime scene and reported from inside the building, where 24 children had been murdered. The picture of the two climbing over the fence from the centre went public on Saturday.
CNN later on Sunday said it had removed the report from its website and issued a statement claiming the two had permission to enter the centre.
CNN learned later that the officials who gave them the access had no authority.
Police would charge the two with trespassing and other possible charges.
