BNP leader Salahuddin Ahmed has submitted a petition to a Meghalaya lower court seeking his bail in a case filed against him for trespassing India.

On behalf of Salahuddin, his lawyer SP Mahanta submitted the bail petition to the registrar office of the court on Friday.

In the petition, Mahanta said Salahuddin needs the bail as he wants to go to another country for better treatment.

"My client is sick enough. We want to take him (Salahuddin) to another country for his better treatment," the lawyer said.

Hearing on the bail petition will be held on May 29, Mahanta said.

Subrata Acharjee, Kolkata correspondent of Bangladesh-based television channel Somoy TV, told this to The Daily Star today.

Yesterday, doctors at a Shillong hospital in India, where Salahuddin is being treated, said his condition was stable but he would have to stay a few more days there due to some minor health complications.

Salahuddin, joint secretary general of the BNP, was shifted to the specialised hospital on May 13 following recommendations of a medical board of Shillong Civil Hospital.

On Thursday, doctors told Indian journalists that the BNP leader had been suffering from urology, heart, kidney, prostate and skin related problems.

That day, BNP Assistant Office Secretary Abdul Latif Jony, quoting Salahuddin's wife Hasina Ahmed, said the senior BNP leader's condition was worsening.

Salahuddin was admitted to the civil hospital on May 11 after police found him loitering in "an unbalanced mental state" in Golf Link area of Shillong. He was missing for about two months.
