Four persons, including three Nigerian nationals, have been arrested for allegedly fraudulently withdrawing Rs20 lakh from the account of a garment export unit in Tirupur near here, police said on Saturday.
The accused were arrested by a team of Tamil Nadu police from Maharashtra and brought to Tirupur on Saturday, they said.
The unit had last month received an e-mail asking it to fill a form with details of its account number and operating secret code. The mail was followed by a call from Delhi by an anonymous person, threatening the unit's account would be blocked, if the owners failed to send the number as sought in the mail.
The unit's owners later lodged a complaint with the police. Based on clues, a police team left for Maharashtra and took one Feroz Khan into custody a week ago from Pune and, on his information, arrested Benkong and Aswin from Mumbai.
Another accused, Rizwan Khan, who worked in an online trading company, was arrested from Pune, they said. It came to light that the gang had drawn Rs 20 lakh through eight accounts and deposited Rs 10 lakh to a service organisation in the city, which was recovered yesterday. The gang was reportedly involved in similar frauds in Delhi and Mumbai, police said, adding further interrogations are on
