HARARE - Police in Zimbabwe have put South African businessman Frikkie Lutzkie's ranch under 24-hour surveillance after government officials called him a threat to state security.

Lutzkie crashed and buried a helicopter a month ago at his ranch in southern Zimbabwe, and authorities believe he has been flying in and out secretly.

Police have now set up a tent to monitor the situation where Lutzkie runs his safari business.

Authorities have been angered by last month's discovery of a helicopter wreck that he had crashed and buried allegedly without informing authorities.

He claims he had the wreckage buried to stop it from catching fire and harming by-standers, but Zimbabwe's civil aviation authority insists he breached national security by flying into the country illegally.

Officials, including the transport minister have accused Lutzkie of flying into the country illegally on several occasions.

The state run Chronicle newspaper said a group of Russian clients are presently at the ranch and the intelligence agency is monitoring those who come and go.

Lutzkie told the paper that he's an innocent investor and that he has not committed any crime.
