A Dhaka court placed models Faria Mahabub Piasha and Mou Akter on a three-day remand each in two separate drug cases.
One drug case against Piasha was filed with Gulshan police station and another was filed against Mou with Mohammadpur police station, said court sources.
Dhaka Metropolitan Magistrate Shahidul Islam and Mohammad Asheq Imam passed the orders on Monday.
Earlier, police produced them before the court and sought a 10-day remand each for interrogation in the cases.
Detective Branch (DB) of Dhaka Metropolitan Police (DMP) police on Sunday night arrested models Piasha and Mou in connection with blackmailing people by uploading objectionable photos.
Piasha was arrested from Baridara area while Mou was nabbed from Mohammadpur area in the capital.
DMP Joint Commissioner (DB) Mohammad Harun-or-Rashid, while addressing the press on Sunday night said that the two models used to invite rich people and their children to different parties at night.
They used to take objectionable photos of them which were later used as weapons for blackmailing.
He said foreign liquor, yaba pills, and shisha were seized from the houses of the models.
However, Mou, while being taken into police custody, claimed to journalists that there was no drug at her house.
She said, I am being framed.
Piasha, former wife of Apan Jewellers owner's son Shafat Ahmed, first came to the discussion after the sensational The Raintree Dhaka Hotel rape incident.
Shafat Ahmed was made accused of raping two female private university students at a Banani hotel in 2018.
Her name resurfaced recently after the suicide of college student Mosarat Jahan Munia.
Piasha was found to be a family friend of the owner of the flat where Munia ‘committed’ suicide earlier in April.
She was interrogated by the police over the incident.
