The Anti-Corruption Commission (ACC) has sent a letter to The Westin Dhaka authorities seeking information on hotel stays of Shamima Nur Papiya, the ousted leader of Jubo Mohila League's Narsingdi district unit.
ACC Deputy Commissioner Shaheen Ara Momtaz sent the letter on Monday afternoon.
Spokesperson for the commission, Pranab Kumar Bhattacharya, confirmed the matter.
"The Westin management has been asked how many days Papiya stayed in the hotel and how much her bill was. In addition, information have been sought about people who visited her there and stayed there," said Pranab.
He added that the hotel's video footage might be sought for the investigation.
ACC sources said earnings and expenditures of a person play a major role in the investigation into illegal wealth. That is why the hotel authorities have been asked about Papiya's expenses.
On Thursday, the ACC decided to probe Papiya's illegal wealth. The investigation officer of the case was appointed on Sunday.
The ACC said not only Papiya but those who helped her amass illegal wealth would also be investigated.
Four people, including Papiya, were arrested by the Rapid Action Battalion (RAB) from Hazrat Shahjalal International Airport on February 22.
RAB filed three cases on charges of possessing illegal weapons and drugs, supplying fake money, drug trade and immoral practices.
The court remanded the arrestees for 15 days each, five days in each three cases filed with Airport Police Station and Sher-e-Bangla Nagar Police Station.
