A senior member of the Burmese opposition party, the National League for Democracy, has been detained by the country's military authorities.
Opposition leader Aung San Suu Kyi is still under house arrest
The chairman of the NLD's Sangaing division, Kyaw San, was arrested on Thursday for allegedly having illegally imported items in his possession.
He was released only four months ago after nearly 10 years in detention.
Rights groups say there are more than 1,300 political prisoners in Burmese jails.
Kyaw San's wife, May Nwet, told the overseas-based Democratic Voice of Burma that some friends of their son, who belong to the Democratic Karen Buddhist Army (DKBA), dropped some goods off at their home without their knowledge.
Kyaw San was taken away as the head of the family, she said, and is currently detained at Insein police station for questioning.
"I don't know if he is going to be released or not," said May Nwet.
Kyaw San was freed from a 10-year incarceration in November, along with dozens of other political prisoners, as part of the fall out from the ousting of former Prime Minister Khin Nyunt.
The NLD won a landslide victory in 1990 but has never been allowed to govern by the military.
