The son of a Canadian couple arrested in China on suspicion of stealing state secrets about military and national defense research says the situation is "mindboggling."

The official Xinhua News Agency said Monday that Kevin Garratt, 54, and Julia Dawn Garratt, 53, were being investigated by the state security bureau in China's northeastern city of Dandong, which borders North Korea.

Son Simeon Garratt, 27 said in Vancouver on Friday that his parents ran a coffee shop and did Christian aid work for North Koreans. He says there's been a mistake in information.

The arrests come after Canada accused a China-sponsored hacker of infiltrating Canada's National Research Council, a top research and development organization.
