BNP leader Salahuddin Ahmed's family has sought the government's help to bring him back from India, report agencies.
"We have always sought the government's help. Nothing is possible without the government's cooperation," wife Hasina Ahmed told the media at her home on Wednesday.
The BNP joint secretary general, who, according to the family, was missing since March 10, was found in the Indian state of Meghalaya.
His wife said on Tuesday she received her husband's phone call from a hospital in Shillong.
Meanwhile, the Indian police said he was arrested from the hill town.
The former BNP state minister was taken to a mental hospital by police as he sounded incoherent but was later shifted to the Shillong Civil Hospital.
Hasina Ahmed, also a former MP, said she will head for Shillong 'as soon as possible'.
"I have filed a visa application...will head for Shillong as soon as I get Indian visa," she told the media.
The BNP leader claimed during police interrogation that he had no recollection of events after being picked up by unidentified men from Dhaka on the night of March 10 and how he reached Shillong, which is less than a 100 km from India-Bangladesh border in Sylhet.
Family sources said Salahuddin's wife, her brother-in-law Mahbubul Karim Bulbul and two others applied for Indian visas to go to Shillong.
Hasina said she could not contact Salahuddin after Tuesday's phone call. "We've come to know he has been transferred to a civil hospital from MIMHANS.
As her attention was drawn that there are some legal complications to bring Salahuddin back home, she said, "We'll take necessary steps once we reach there. I want the government's cooperation in this regard. Nothing will be possible to this end without government' s cooperation."
