One of Vietnam's
best-known dissidents, Catholic priest Nguyen Van Ly, has been
re-arrested more than a year after getting medical leave from prison.
Sources told journalists he had been escorted by police from a church in the Hue area of central Vietnam.
The government said he had been distributing anti-government writings.
His eight-year prison sentence for subversion had been
suspended in March of last year to allow him to seek treatment for a
brain tumour.
The condition of his health was not clear following news of his re-arrest on Monday.
Fr Ly, who is in his 60s, suffered two strokes in 2009 that
left him partly paralysed, and Western governments had demanded
repeatedly that he be freed.
His original trial made news headlines as he tried to read
out a poem criticising Vietnam's communist authorities and was muzzled
by police.
He has spent more than 15 years in prison since 1977.
In 2009 a group of 37 US senators wrote to Vietnam's President Nguyen Minh Triet, calling for the priest's release.
The Roman Catholic clergyman was a founding member of Bloc 8406, a pro-democracy movement launched in 2006.
