Kolkata: A senior pharmaceutical company official from Kolkata lost over Rs 1. 1 crore in a fake kola nut online trading scam. Kola nuts have various uses in the pharmaceutical industry. The cyber crooks used the name of a top UK-based pharmaceutical company, created their fake website and trademark to dupe the official, a resident of Hiland Willows in Newtown. The victim alleged the fraudsters orchestrated a two-week-long scheme using forged documents. On May 1, he allegedly received an email, mimicking the original email address of the company. The sender of the email presented lucrative business opportunities in kola nut trading. The frauds expanded their communication to WhatsApp, using international numbers. They introduced Guha to persons claiming to be kola nut sellers from northeast, who contacted him using Indian numbers. The fraudsters initially delivered small quantities of kola nuts to gain his trust. Guha transferred the swindled amount to various bank accounts, only to be duped.
