MUMBAI, May 18 -- A 26-year-old Ghanaian woman residing in Nalasopara East was arrested on Friday for making mephedrone (MD) at home. Police said they happened to visit her house when they were carrying out a drive checking for Bangladeshi illegal immigrants in the area. They seized raw materials worth Rs.5.6 crore from the premises. During the drive, teams headed by police inspectors Vijay Jadhav and Rahul Phad reached Pragati Nagar in Nalasopara East. "We learnt two foreigners were in a chawl. When the team visited a corner room, we found a woman inside and upon inquiry, realised she was cooking MD," said a police officer. During questioning, she told the police her name was Rita Fati Kurebewei, 26. Her male friend, Henryuchenna Uwakwe, fled as soon as he suspected the police arrival. The police did not find her visa to permit her to stay in the country. Kurebewei was booked under relevant sections of the NDPS Act and arrested. Vinay Dalvi...
